Comment on the "n=3" section of "Proof of Fermat's Last Theorem for specific exponents"
I have a request to the editor(s) of this article. All this refers to the "n=3" section of the Fermat article.

The present text states that "A crucial lemma shows that if s is odd and if it satisfies an equation s**3 = u**2 + 3v**2, then it can be written in terms of two coprime integers e and f ...". But no proof is given of this crucial lemma. I would appreciate seeing the proof either in the Wikipedia article, or as a personal communication to me. Thank you for your attention.
