21.19 PermGroupOps.PgGroup

PermGroupOps.PgGroup( G )

This function converts a permutation group G of prime power order p^d into an ag group P such that the presentation corresponds to a p-step central series of G. This central composition series is constructed by calling CentralCompositionSeriesPPermGroup (see CentralCompositionSeriesPPermGroup). An isomorphism from the ag group to the permutation group is bound to P.bijection.

There is no dispatcher to this function, it must be called as PermGroupOps.PgGroup.
