GAP package NQ: This package provides an interface to the ANU Nilpotent Quotient Program for the computation of nilpotent factor groups of finitely presented groups. It requires the presence of the GAP package polycyclic. This package provides: Computation of factors along the lower central series of a finitely presented group. Computation of nilpotent groups satisfying a given finite set of laws. Computer algebra system (CAS). http://www.sigsam.org/software/anunq.html
