hello world,
it seems to me that there's a problem with wreath products:

GAP4, Version: 4.4.5 of 13-May-05, i686-pc-linux-gnu-gcc
gap> G := WreathProduct(CyclicGroup(3),Group((1,2,3),(4,5,6)));
<group of size 6561 with 3 generators>
gap> Gc := Image(IsomorphismPcGroup(G));
Group([ f1, f2, f3, f4, f5 ])
gap> Size(Gc);
243
gap> G := WreathProduct(CyclicGroup(IsPermGroup,3),Group((1,2,3),(4,5,6)));
<permutation group of size 6561 with 8 generators>
gap> Gc := Image(IsomorphismPcGroup(G));
Group([ f1, f2, f3, f4, f5, f6, f7, f8 ])
gap> Size(Gc);
6561
