It says that Bevaprime has been suggested as a name for a prime that contains at least 1 thousand million digits. However, as a Megaprime contains at least 1 million digits, surely the logical extension to 1 thousand million digits would be a Gigaprime? 79.77.203.214 ( talk) 21:04, 13 March 2010 (UTC)
We know that the smallest 1,000,000,000-digit number is 10^999,999,999. (For short, we'll call this number Beva.) We know it is not prime because it is even. Beva plus 1 is divisible by 11 and obviously not prime. Beva plus 2 is even. Question: Does Beva plus 3 have any known factors?? Georgia guy ( talk) 13:43, 14 June 2012 (UTC)
? forprime(p=2,10^8,if(Mod(10,p)^999999999+3==0,print(p))) 23 ?
? forprime(p=2,10^8,if(Mod(10,p)^999999999+7==0,print(p))) 647 ?
Is the scope of this page only numbers where primality has been proven or also PRPs? If the latter, then it might be worth mentioning 10999999 + 593499. -- Toshio Yamaguchi 13:53, 1 March 2013 (UTC)
I added a table containing all known megaprimes and mega PRPs. It is not complete yet. I will add the missing entries as time permits it. -- Toshio Yamaguchi 08:08, 8 April 2013 (UTC)
I don't understand what this graphic is showing. What do the x and y values stand for? For example, what does the number 9 on the x-axis denote? The y-axis seems to be the number of megaprimes found in a particular year, although the numbers don't seem to be correct. For example, if 12 means 4 megaprimes have been found in 2012, then this seems to be incorrect, because according to http://primes.utm.edu/primes/lists/all.txt, which the graphic seems to be based on, 18 megaprimes were discovered in 2012. -- Toshio Yamaguchi 09:12, 8 April 2013 (UTC)
I note that a dozen of the entries in the table are expressed in terms of something that uses phi. What specifically does this mean? I doubt it's the golden ratio... DS ( talk) 17:14, 23 April 2017 (UTC)
What if a Teraprime was used to describe primes over 1012 ? Also, bevaprime is not in use currently, there are no known primes above 24 million digits. YeetPlus ( talk) 18:52, 25 September 2020 (UTC)
I request only list primes with more than 2,000,000 digits, because there are too many megaprimes nowadays. Thingofme ( talk) 01:31, 17 December 2021 (UTC)
When the primes are confirmed by Prime Pages, sometimes it's still a PRP. Thingofme ( talk) 13:56, 13 May 2022 (UTC)
I'm going to split out the table into its own article. I assume this is noncontroversial (the table starts at 2,000,000 digits, not 1,000,000, and megaprime is not a synonym for large prime, as well as not being a widely used term in general). Dan Bloch ( talk) 19:29, 21 June 2022 (UTC)
