D.8.6.7 factorMain

Usage:

factorMain(f); where f is a polynomial

Purpose:

compute the factorization of the squarefree polynomial f over Q(a)[t], minpoly = p(a).

Return:

list with 2 entries

_[1] = factors, first is a constant _[2] = multiplicities (not yet implemented)

Assume:

basering = Q[x,a], representing Q(a)[x]. An ideal mpoly must be defined, representing the minimal polynomial (it might be 0!).

Note:

outdated, use factorize instead
