Just a short answer for now: it's been in the TODO list for a while to
have representation matrices for the Hecke algebra (there might be a
ticket about this, and almost certainly a note in the road map). So
progress in this direction is surely welcome, especially if this can
be done uniformly for symmetric groups versus hecke algebras and type
A versus generic type.
By the way, this could be an occasion to make those methods of the
symmetric group / hecke algebra. Something like:
sage: SymmetricGroup(5).representation([3,2], "seminormal")
As for speed: do you think the limitation comes from the cost of the
arithmetic in the base field, or from the linear algebra?
Cheers,
Nicolas
