@ DocWatson42 Apologize for pinging you here. I have done some tests: {{ multiple image}} on the right and left (along with {{ clear}}). What I meant in the last paragraph is that if I put it on the left side remains completely fine for normal size; on the other hand, I considered that it will display the sandwiching images in your window. [1]

Meanwhile, putting on {{ clear}} will give you ugly blank space [2], and putting on the right side, on the other hand, will push down the images, as you mentioned it before in your talk page. [3] Dedhert.Jr ( talk) 02:07, 16 February 2023 (UTC) reply

I'm okay with the sandwiching (and the first option); for the record, the sandwiching starts happening at about 3400 pixels (two-thirds width of my display). — DocWatson42 ( talk) 02:13, 16 February 2023 (UTC) reply

@ DocWatson42 Good. I will change it on the real article, putting it on the left side. Would you mind? Dedhert.Jr ( talk) 02:15, 16 February 2023 (UTC) reply

Nevermind. MOS:RESOL prevents it. I think it's fine using gallery tag. Dedhert.Jr ( talk) 02:44, 16 February 2023 (UTC) reply

Okay. Oh, well (for you—my sympathies). :-/ — DocWatson42 ( talk) 03:04, 16 February 2023 (UTC) reply

Hi. Thank you for your recent edits. An automated process has detected that when you recently edited List of disproved mathematical ideas, you added a link pointing to the disambiguation page Springer. Such links are usually incorrect, since a disambiguation page is merely a list of unrelated topics with similar titles. (Read the FAQ • Join us at the DPL WikiProject.)

Hi Dedhert.Jr. Thanks for your work tidy up citations. Can I suggest you turn on the error messages associated with {{ sfn}} and {{ harv}} templates? They are off by default, but Category:Harv and Sfn template errors shows how to turn them on. If you have any questions just ask. -- LCU ActivelyDisinterested ∆ transmissions∆ ° co-ords° 12:11, 19 October 2023 (UTC) reply

@ ActivelyDisinterested Hi. Thank you for the information. It happened as I was reading a page, and I wondered how is the error possible exist. Can you tell me why? Dedhert.Jr ( talk) 12:14, 19 October 2023 (UTC) reply

This is about edits like this one [4], if you had the error messages on you would likely have noticed that Berkelamp and Conmway should be Berlekamp and Conway. Simple spelling mistakes, but because the error messages are off they are difficult to see. -- LCU ActivelyDisinterested ∆ transmissions∆ ° co-ords° 12:18, 19 October 2023 (UTC) reply

@ ActivelyDisinterested Weird. Mine is different than that. In the article Mobius–Kantor graph mentions the harvtxt error

(Coxeter 1950) harv error: multiple targets (2×): CITEREFCoxeter1950 (help).

and I have no idea how to deal with this, even though I have read the category you linked above. Dedhert.Jr ( talk) 12:22, 19 October 2023 (UTC) reply

The templates create hyperlinks to a full cite, if there is no cite to link with you get a "no target error" but if there are multiple cites to link with you get a "multi-target error".

The issue with Mobius–Kantor graph is that the cite for "Coxeter 1950" appears as reference #4 and as the first cite in the References section.

Either the one in the Reference section should be removed, or reference #4 could be converted to use {{ sfn}}. -- LCU ActivelyDisinterested ∆ transmissions∆ ° co-ords° 12:30, 19 October 2023 (UTC) reply

@ ActivelyDisinterested Thank you for suggestions. But I don't think it's a good idea either to change to sfn or remove the Reference section, as the article already use full citations. @ David Eppstein, as the user who created the article, would you like to assist me? Sorry for pinging. Dedhert.Jr ( talk) 12:44, 19 October 2023 (UTC) reply

It makes extensive use of {{ harvtxt}} templates in the article text. These require the cites that appear in the References section, so they can't be removed.

My point was that a cite should only appear once, but the "Coxeter 1950" cite appears twice (causing the error message). -- LCU ActivelyDisinterested ∆ transmissions∆ ° co-ords° 12:58, 19 October 2023 (UTC) reply

I changed it to use sfn. It had two inconsistent citation styles (inline full citations, and inline parenthetical citations in a deprecated format) combined with article text referring to full citations later, so the most consistent choice was to use sfn for the inline citations and keep the full citations later. — David Eppstein ( talk) 15:22, 19 October 2023 (UTC) reply

Hi there, I'm pleased to inform you that I've begun reviewing the article Square pyramid you nominated for GA-status according to the criteria. This process may take up to 7 days. Feel free to contact me with any questions or comments you might have during this period. Message delivered by ChristieBot, on behalf of David Eppstein -- David Eppstein ( talk) 18:23, 2 November 2023 (UTC) reply

Ok, I've made a first pass through the article and made some suggestions. See Talk:Square pyramid/GA1. — David Eppstein ( talk) 01:49, 3 November 2023 (UTC) reply

@ David Eppstein Thank you. I will try my best to improve them. And for some reason, this is my first GAN, and I'm actually surprised that you have picked this article to review in a moment. Dedhert.Jr ( talk) 01:57, 3 November 2023 (UTC) reply

I was surprised that I hadn't edited the article at all (significant contributors to articles are forbidden from reviewing them) but I try to review mathematics nominations when I can. Anyway, please ping me when you're ready for me to take another look at the article after your edits. — David Eppstein ( talk) 05:49, 3 November 2023 (UTC) reply

Got it. Dedhert.Jr ( talk) 07:32, 3 November 2023 (UTC) reply

The article Square pyramid you nominated as a good article has passed ; see Talk:Square pyramid for comments about the article, and Talk:Square pyramid/GA1 for the nomination. Well done! If the article has never appeared on the Main Page as a "Did you know" item, and has not appeared within the last year either as "Today's featured article", or as a bold link under "In the news" or in the "On this day" prose section, you can nominate it within the next seven days to appear at DYK. Bolded names with dates listed at the bottom of the "On this day" column do not affect DYK eligibility.

Congratulations! I've been following your progress on Square pyramid over the last few months and have seen the amount of work you've put into it; you should be proud of your accomplishment. I also believe I still owe you a copyedit on it. Even though David Eppstein went through and got all of the major points, I'll take a look myself and see if there isn't anything else I can do to help. — TechnoSquirrel69 ( sigh) 09:18, 20 November 2023 (UTC) reply

@ TechnoSquirrel69 Thanks for some minor copyedit, and I can't do this without your assistance. Furthermore, thanks to @ David Eppstein who reviewed this article until pass to GA. However, the current problem I have to deal with is my writing skills, and I definitely worry about the warning by WP:CIR. Does the fluency of writing actually include in that essay as well? I appreciate your answer as I might probably have some articles having the GA status (or maybe featured class). Dedhert.Jr ( talk) 09:50, 20 November 2023 (UTC) reply

Thanks for working on the Derivative article. XOR'easter ( talk) 19:38, 16 December 2023 (UTC) reply

@ XOR'easter Your welcome. I'm not an expert in this, anyway. Sadly, I haven't finished yet. I'm thinking about the definition part that states the usage of the limit concept, but it doesn't mention the analogous concept of the tangent line's slope and instantaneous rate of change. Also, is it possible to create subsections about that definition, including the limit and the hyperreal? Dedhert.Jr ( talk) 07:18, 17 December 2023 (UTC) reply

I was thinking myself about moving those two definitions together to avoid having a super-short section. So, I went ahead and did that. The idea that the derivative is the slope of the tangent line can probably go in the "As a limit" subsection. XOR'easter ( talk) 16:39, 17 December 2023 (UTC) reply

@ XOR'easter Looks better. But I didn't see it mentions the "instantaneous of rate" as well in the section of limit. Also, the definition by hyperreals remains lack of sources. I have looked up the sources yesterday, and it seems that I couldn't find them until nowadays. Dedhert.Jr ( talk) 03:10, 18 December 2023 (UTC) reply

Hi Dedhert.Jr,

Since you tagged this as C-class, I was curious: in your opinion, in what ways does the article fall short of the B-class criteria? (I ask in the hope of planning further improvements.)

Thanks, JBL ( talk) 20:00, 14 January 2024 (UTC) reply

@ JayBeeEll, thank you for the question. I'm not actually expert in group theory, but my opinion about this article is somewhat technical, and may not be understand by readers. The assessment of the article has already been covered by our assessment in WPM, or WP:QUALITY in general.

Also, does all of the articles about group theory is unavoidably extremely technical? If there is any mistake, please remind me. Thank you. Dedhert.Jr ( talk) 01:14, 15 January 2024 (UTC) reply

Thanks, I figured technicality was the problem, but I wanted to check that there weren't any other major weak points I'd overlooked. The literature around reflection groups in general is tilted heavily towards professional mathematicians (or on the low end doctoral students in mathematics), it is only glancingly touched on in an undergraduate curriculum; and parabolic subgroups are not the most accessible part of the theory (though not the least either). I think with more work I might be able to make this article largely accessible to, say, an undergraduate who has completed a course in group theory (an appropriate audience per WP:ONELEVELDOWN), but probably not much further than that. Thanks for your input! -- JBL ( talk) 17:22, 15 January 2024 (UTC) reply

On 20 January 2024, Did you know was updated with a fact from the article Square pyramid, which you recently created, substantially expanded, or brought to good article status. The fact was ... that square pyramids can have different shapes, and pyramidologists have put forward multiple theories on which of these shapes was used for the Egyptian pyramids? The nomination discussion and review may be seen at Template:Did you know nominations/Square pyramid. You are welcome to check how many pageviews the nominated article or articles got while on the front page ( here's how, Square pyramid), and the hook may be added to the statistics page after its run on the Main Page has completed. Finally, if you know of an interesting fact from another recently created article, then please feel free to suggest it on the Did you know talk page.
