Lemma 3.2 (Kantor-Luks)(CFSG) For G = G/K, where K [??] G [less than or equal to] Sym([OMEGA]), given H,N [less than or equal to] G such that H normalizes N, one can find [C.sub.H](N) (including, in particular, Z(H)) in polynomial time.
Nevertheless, in [25, [section]4], with the help of Kantor's Sylow machinery and thus CFSG (Theorem 3.1(xi)), the problem was asserted to be in polynomial time; since the proof was omitted in [25] due to space limitations, we include it here.
Lemma 3.16 (CFSG) Problem 16 is solvable in time polynomial in [absolute value of [OMEGA]], n, log q and [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII.].
Remark (i) If we hypothesize that G [member of] [[GAMMA].sub.d] in Problem 16, then the problem can be solved without invoking CFSG by using the method of Kantor and Taylor from [26], in place of Theorem 3.1(xi), to find Sylow subgroups.
For this, we appeal to the following fact from CFSG: For every nonabelian simple group T, we have [absolute value of Out(T)] = O(log [absolute value of T]) (see, e.g., [27]).
