I think Marco (who works with me) took my suggestion to simplify his problem code as much as possible before posting a little too literally. Marco, send in something closer to what you showed me yesterday (which was about factorization of polynomials of degree 4 in F[X,Y,Z] with F a quite small finite field).
Vincent, if you are still in Warwick today Marco could show you his code directly.
