1376:, I have just posted to the nominator's talk page that they need to take action, otherwise the nomination will likely close in a matter of days. May I suggest that if nothing is done, the nomination be closed by the end of September, or if you want to be exceptionally lenient, no later than October 4, two months after they posted
1173:"The following results are proved in Blumethal's book." – Some introduction instead of this would be useful as well as for previous point. Also the whole section probably should be largely reformatted. First question I come up with looking on the section is "why is it here?" and the second one is "what's going on here?".
1170:"A proof of this theorem in a slightly weakened form (...) is in ." – This information really has little encyclopedic significance. Simple inline citation would suffice. More importantly, theorem shouldn't just hang in the air. Please, provide some summarized info about its significance and usages.
248:, who destroyed all references to higher dimensions, which are crucial to the point of the article. Now someone in another forum is telling me that my link to this article is not much appreciated because it doesn't go into higher dimensions. I've restored the material that was destroyed.

The Cayley-Menger determinants given by the principal submatrices with elements of the 4, the first 3 and the first 2 lines satisfy the embedding conditions of
Knowledge. However, the remaining three triangles of the potential tetrahedron do not fulfill the triangle inequality.

In general, all issues seem easily fixable, except for "Characterization via ... determinants" section. This one seems to need a lot of improvement. Please, update here whenever you fix something or reply to comments. I'll look into it again later.
942:"Cayley–Menger determinants, named after Arthur Cayley and Karl Menger, are determinants of matrices of distances between sets of points." – why do the last column and row consist of ones then?

516:, except for plot summaries and that which summarizes cited content elsewhere in the article, must be cited no later than the end of the paragraph (or line if the content is not in prose).
936:"affinely independent, iff they cannot ..." – using iff clause is not recommended for definitions. Simple if is ok here. Also I'd suggest not to write "A iff B iff C" and keep it simpler.

Thanks for your very detailed review. I just want to say that the first sentence was an astonishing coincidence, and there is no copyright violation. Now I'll have a cool story to tell.

Unfortunately, that's wrong. The results presented by
Knowledge only roughly reflect Blumenthal's work and contain errors.

Since I have no time to update the page, I would have to leave it at that for now. Maybe later I'll update it as suggested.
