Dear GAP Forum,
I have the following question: Given a (finite) pc-group G of rank r, how
to construct (with the help of GAP) 'the largest' group H of the same rank,
such that H/Z(H) is isomorphic to G? Here 'the largest' means that every
other group of rank r with the above property is a homomorphic image of H.
Any suggestion (or an example or a reference) would be appreciated.
With best regards,
