Comment (by darij):
So I assume this one is a real issue for a change:
{{{
sage: Q = DiGraph({1:{2:['a','b']}, 2:{3:['c']}}).path_semigroup()
sage: M = Q.I(GF(3), 3)
sage: N = Q.S(GF(3), 3)
sage: M.quotient(N)
Representation with dimension vector (2, 1, 0)
sage: R = _
sage: R(M.an_element())
# wait
RuntimeError: maximum recursion depth exceeded while calling a Python
object
}}}
Also, please double-check my edits.
