The line `R.<a, c> = QQbar[]; factor(a^2 - 2*c^2)` raises a ValueError: variable name '@c' is not alphanumeric
while the same line with `c` replaced with `b` works fine. This happens in a local installation of Sage 10.4 (and 10.5.beta0), but also on the SageCell. -- Peter Mueller -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
