The GAP package TwistedConjugacy

by Sam Tertooy sam.tertooy@kuleuven.be

About

The TwistedConjugacy package provides methods for solving the twisted conjugacy problem (including the “search” and “multiple” variants) and for computing Reidemeister classes, numbers, spectra, and zeta functions. It also includes utility functions for working with (double) cosets, group homomorphisms, and group derivations.

These methods are primarily designed for use with finite groups and with PcpGroups (finite or infinite) provided by the Polycyclic package.

This package requires GAP version 4.14 or later. The extension for PcpGroups requires Polycyclic version 2.16 or later.
