Yes, when a facade set A models a subset of B, then I agree that a

Hi,
About your bug, I don't know if someone is looking after
SchubertPolynomialRing, from what I see it is mostly sent to symmetrica. I
see what is causing the problem, when creating an element, the index is
sent to Permutation_class which doesn't check if the list is a valid
permutation.
When I

It will also slow things for SchubertPolynomialRing if we do the check for
each new element. The problem is that when the permutation is not correct
and someone try to expand the polynomial, then instead of doing a usual
exception, it stops the program ! I think it comes from something with
symmetr
