Package Archives for Download

The ANUPQ package is available in several formats:

The current version removes deprecated code, completely updating it for the new package loading mechanism of GAP 4.4. It is not backward compatible with GAP 4.3.

There is an improvement to IsPqIsomorphicPGroup suggested by Marco Costantini that Jack Schmidt helped us get right(!) but no bugfixes in this version. If the user has not updated from GAP 4.3 (at least fix4), then they must continue to use the previous version of the ANUPQ package (version 2.2) together with AutPGrp 1.1. However, it is strongly recommended that the user upgrades their GAP installation.
