You're right - thanks. I have a question about the output of this though. F5 has 4 distinct eigenvalues (one of them has multiplicity 2). F5.eigenspaces() correctly returns the eigenspaces defined over QQ(zeta5). There are two eigenvalues not in QQ(zeta5) but the output simply indicates "(a2,[ ])". What does this means?
