Dec 30, 2012 at 18:09	comment	added	Derek Holt		Yes that is indeed a more direct argument!
Dec 30, 2012 at 17:38	comment	added	Mart		@Geoff Robinson: Thanks. By Derek's answer if $S\unlhd G$ with $S$ simple and $G\leq Aut(S)$, then $p$ is prime divisor of $S$. Whether by your answer it implies that $p$ is prime divisor of $S$?
