The subgroup functions compute subgroups or series of subgroups from
given ag groups, e.g. PRump (see PRump) or ElementaryAbelianSeries
(see ElementaryAbelianSeries). They return group records described in
Group Records and Ag Group Records for the computed subgroups.
All the following functions only work for ag groups. Subgroup functions which work for various types of groups are described in Subgroups. Properties and property tests which work for various types of groups are described in Properties and Property Tests.
