# Polycyclic

### Bettina Eick Werner Nickel

### Description

This is a prerelease (version 1.0) of the share package `Polycyclic' written for GAP 4. It provides a basis for working with polycyclic groups. The features of this package include

- creating a polycyclic group from a polycyclic presentation
- arithmetic in a polycyclic group
- computation with subgroups and factor groups of a polycyclic group
- computation of standard subgroup series such as the derived series, the lower central series
- computation of the first and second cohomology
- a variety of other features

We release this version because some people have expressed interest in using the package. We also hope that there are people who would like to try it and are willing to give us feed back about the package.

### (Bug) reports

If you use `Polycyclic', we would like to know. A short email to one (Bettina Eick, Werner Nickel) or both of us would be nice.

Any comments about the package are very welcome. If you have found important features missing or if there is a bug, let us know and we will try to address it in the next version of the package.
