[edit] Question about proof

The last line: NH(P) ≤ NG(P) ≤ M so M = H seems to unnecessarily include it's 1st expression NH(P) as it is not used by the proof. It only confuses. —Preceding unsigned comment added by 79.180.4.184 (talk • contribs)

It seems to me N_H(P) is needed. The goal of that part is to get that N_H(P) <= M, so that M <= H = N_H(P) M <= MM = M, so M = H. I expanded the proof a little to make it clearer how each part is used. JackSchmidt (talk) 14:05, 19 December 2007 (UTC)
