FInally! http://trac.sagemath.org/sage_trac/ticket/13724
There are still broken things, seems to behave correctly:
{{{
sage: A3 =
CartanType("A3")
sage:
A3.cartan_matrix()
[ 2 -1 0]
[-1 2 -1]
[ 0 -1 2]
sage: A3r =
A3.relabel({1:2,2:3,3:1})
sage: A3r.cartan_matrix()
[ 2 0 -1]
[ 0 2 -1]
[-1 -1 2]
}}}
Mainly, the doctest of type_relabel.py compains about some not correctly
inherited methods. I have the impression that it has to do with dynamic
classes, which are beyond my knowledge. Could I get any hint, please?
Cheers,
Jesús Torrado
