[GAP Forum] An overgroup of Sylow in PSL( 2, 7^3 )

[Hulpke,Alexander]

Dear Forum,

I think the problem arises from the documentation of 'IntermediateSubgroup'.
> I need to construct a proper subgroup of PSL( 2, 7^3 ) that contains a

> According to the manual, IntermediateGroup returns `fail' if the subgroup

Yes, this is a bug. I will fix it for a future release.

Best,
