Hi all,

I have ay simple question.  I am utilizing GAP in a way that necessitates
the construction of explicit matrix representations of group generators.
These matrices can in my case depend on things like x^(1/4), e.g.
ER(ER(x)).  However, the ER command can only deal with rational arguments,
so ER(ER(16))=2 works fine, but ER(ER(8)) is problematic.  I have looked
through the documentation and don't see an obvious way to get around the
problem.  Can anyone help?
