Description
This package provides algorithms 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 
-  computation of group extensions
-  computation of normalizers and centralizers
-  solutions to the conjugacy problems for elements and subgroups
-  computation of Torsion and various finite subgroups
-  computation of various subgroups of finite index
-  computation of the Schur multiplicator, non-abelian the exterior square and the non-abelian tensor square
(Bug) reports
If you use Polycyclic, we would like to know.
 A short email to one 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 as soon as possible.
Installation
  
  In order to install and use Polycyclic,
  your also need to install both Alnuth and
  AutPGrp. The former contains  
  methods for algebraic number theory, the later for computations of
  automorphisms of p-groups; both are required by Polycyclic for
  various operations.
  The README file describes the installation
  of the Polycyclic package. 
  
  For the installation of Alnuth and AutPGrp, follow the instructions in their
  respective manuals.
  
  Online Documentation
  
  
  The manual of Polycyclic is available as
       PDF and
       HTML.
  
  If the package has been installed properly, the manual is
  also accessible through the GAP online help.
