Comment (by mmarco):
I guess i am missing something, but that's what i get with the new patch:
{{{
sage: g=libgap('FreeGroup(2)')
gap: halfing pool size.
sage: (a,b)=g.GeneratorsOfGroup()
sage: h=g/libgap([a^2,b^2,a*b])
sage: h
<fp group on the generators [ f1, f2 ]>
sage: x=h.GeneratorsOfGroup()[0]
sage: x
f1
sage: x^2
f1^2
sage: x^3
f1^3
sage: x.Order()
---------------------------------------------------------------------------
