Given g 2G, the ,centralizer, of g in G is the subgroup C G(g) := fa 2G jag = gag. Given S G, the ,centralizer, and the normalizer of S are the subgroups C G(S) := fa 2G jag = ga 8g 2Sgand N G(S) := fa 2G jaSa 1 = Sg. Two elements g;h 2G are conjugate when there exists a 2G such that h = aga 1. The conjugacy class of g in G is the set K G(g) := faga 1 ja 2Gg.

By the Normalizer/Centralizer theorem, $\frac{N_{G}(H)}{C_{G}(H) }= \frac{G}{C_{G}(H)} \ $ is isomorphic to a subgroup of $Aut(H)$ and so is finite. Now we note that if $M \ \trianglelefteq \ G \ $, $M$ is abelian and $M \leq C_{G}(H) \ $, then $HM$ is abelian and normal in $G$, but $H$ is maximal abelian normal so $HM\leq H \ $ and then $M\leq H \ $.
