This package provides various algorithms for computations with
|
||
|
polycyclic groups defined by polycyclic presentations. 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, the non-abelian exterior
|
||
|
square and the non-abelian tenor square
