I'll be reviewing this article, although I have edited it before, with the reason below. Following comments:
The lead summarizes the whole article, but one problem is the source of its historical discovery. In order to make the readers, especially if they particularly are in favor of researching even more about this polyhedral article, can we simply link it more specifically rather than just at the beginning of the journal? Also, is it possible now to add {{ infobox polyhedron}}, as the article describes the number of vertices, edges, faces, and types of this polyhedron, together with the net from Branko's source? Dedhert.Jr ( talk) 04:16, 19 February 2024 (UTC)
Construction: This section fully describes how the Schonhardt polyhedra are constructed, but it does not mention what is the angle of one of two equilateral triangles rotated. I do think we can use the first source in the lead to mention it, or was it fully restricted by WP:PRIMARY so we should find other sources that are cited? Dedhert.Jr ( talk) 04:16, 19 February 2024 (UTC)
Properties: Each Schönhardt polyhedron has six vertices, twelve edges, and eight triangular faces: Why "each"? This section also mentions the convex hull, but I do not have a good visualization about this after I read this; is it possible to explain more specifically? Also, the source does not mention that both the Schonhardy polyhedron and its convex hull are combinatorially equivalent to the regular octahedron [1]. I wonder if is there some mensuration of this polyhedron, such as surface area or volume. Is there a symmetry group? I hope they can be included here. Dedhert.Jr ( talk) 04:16, 19 February 2024 (UTC)
Properties/Impossibility about triangulation: It is impossible to partition the Schönhardt polyhedron into tetrahedra whose vertices are vertices of the polyhedron. Umm, "vertices of the polyhedron"? What? Does it refer to every polyhedron in general? I don't get it. Dedhert.Jr ( talk) 04:16, 19 February 2024 (UTC)
Properties/Jumping polyhedron: The cited source in this section does explain the definition of "jumping polyhedron". However, it does not mention the Cauchy rigidity theorem. Did I miss something here? Dedhert.Jr ( talk) 04:16, 19 February 2024 (UTC)
Related constructions: Rambau (2005) has a dead link, and I cannot check the verifiability. Also, the second paragraph mentions there is no internal diagonal of the resulting polyhedron by such construction. Frankly, why does Czasar tetrahedron suddenly appear here? Does it solely explain what are other examples of polyhedrons with diagonal entirely on the outside? Dedhert.Jr ( talk) 04:16, 19 February 2024 (UTC)
Applications: The section explains its usage in the proof of NP-complete problem, but I wonder why there is an image of tensegrity here? If that's the case, can we add the applications in tensegrity as well? Note that I have edited the article before, trying to tidy up one reference in the caption image. One problem is the source is Lulu, a self-publisher; is it fine? Dedhert.Jr ( talk) 04:16, 19 February 2024 (UTC)
Overall, the article has met some criteria according to WP:GACR, with some comments of suggestions to improve the article and meet the criteria even more. Will respond to them swiftly. Dedhert.Jr ( talk) 04:16, 19 February 2024 (UTC)
