[GAP Forum] problem with AutomorphismGroup

[Markus Szymik]

Dear Forum,

I am trying to compute automorphism groups of p-groups, 
and GAP responds with an error message I don't understand. 
For example,

	AutomorphismGroup(DihedralGroup(8));

results in:

	...
	RuntimeError: Gap produced error output
	Function: number of arguments must be 1 (not 2)

The command works fine for all groups of order less than 8.
What is wrong here?

Thanks,

Markus
