Comment:
With the changes to the representation string and by fixing a silly error
I made earlier (pushed one commit), there's just one failure remaining. It
seems that the action from a finite field onto the general linear group is
not implemented; I think that should be possible. E.g.:
{{{
sage: G = GL(3,5); F = G.base_ring()
sage: F(2) * G.one()
Traceback (most recent call last):
...
TypeError: unsupported operand parent(s) for '*': 'Finite Field of size 5'
and 'General Linear Group of degree 3 over Finite Field of size 5'
}}}
Should this be handled on this ticket as well or should we open a separate
ticket? (Personally, I'm for a separate ticket...)
