# Factorization of non-commutative Laurent polynomials

Hi, can Sage factorize non-commutative Laurent polynomials in several variables?

By those polynomials I mean elements in the group algebra Z[F(n)], where Z is the integers and F(n) is the free group on n letters.

(The case with Z/2- instead of Z-coefficients would also be interesting.)

Thank you!
