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?
