Talk:Fundamental Theorem of Finite Abelian Groups/Lemma 4

Was this taken from Gallian, by the way? Cause I have the same crappy not-proof for this lemma in my copy of his Contemporary Abstract Algebra... --Alec (talk) 23:45, 4 May 2011 (CDT)


 * Alec, I feel your pain on this one. When my group theory notes finally rotate back to the top of my organically-shifting, tottering tower of paper to the side of me, I'll dig out the work that goes towards this. The working is far more long-winded than this and tedious to document (includes matrix manipulation work) but it forms a highly instructive whole. But don't hold your breath, I have this so-exciting-it's-frightening topology work I'm ploughing through minutely at the moment which will take a few weeks (months?) yet. --prime mover 16:22, 5 May 2011 (CDT)
