7.7.12.0. facShift
Procedure from library ncfactor.lib (see ncfactor_lib).

Usage:
facShift(h); h a polynomial in the n'th shift algebra

Return:
list

Purpose:
compute all factorizations of a polynomial in the nth shift algebra

Theory:
h is mapped to the $n$th Weyl algebra and then factorized there. The factorizations are mapped back (S_n in subalgebra of Weyl algebra).

Assume:
basering is the nth shift algebra

Note:
Every entry of the output list is a list with factors for one possible factorization.

Example:
