69 The Polycyclic Quotient Algorithm Package

This package is written by Eddie Lo. The original program is available for anonymous ftp at math.rutgers.edu. The program is an implementation of the Baumslag-Cannonito-Miller polycyclic quotient algorithm and is written in C. For more details read BCMa,BCMb, Section 11.6 of Sims94and Lo.

This package contains functions to compute the polycyclic quotients which appear in the derived series of a finitely presented group.

Currently, there are five functions implemented in this package:

CallPCQA (see CallPCQA),
ExtendPCQA (see ExtendPCQA),
AbelianComponent (see AbelianComponent),
HirschLength (see HirschLength),
ModuleAction (see ModuleAction).
