[GAP Forum] computing automorphism groups

[Robert Heffernan]

Hi,
I'm computing the automorphism groups of finite groups (particularly,finite perfect groups) but GAP seems to be taking an awful long timeto do this.
For example, the following has been running for several hours now:
A:=AutomorphismGroup(PerfectGroup(168,1));
The machine I am running this on is quite decently specced.  Also, Istarted gap with the following:gap -o 1000Mto give GAP plenty of memory to work with.
Should I be expecting such a delay?
thank you,Bob
