Comment:
Hi,
your code looks good to me. The only issue I could see is that it was
taking the
transpose of the matrix A before computing coroots hence constructing
roots.
(This is probably a leftover of my previous implementation.) I am not sure
why I
did not use CartanMatrix back when I coded this first; was it already in
sage?
S.
