CommutatorFactorGroup( G )
CommutatorFactorGroup
returns a group isomorphic to G/<G>^prime
where <G>^prime is the derived subgroup of G (see
DerivedSubgroup).
gap> s4 := AgGroup( Group( (1,2,3,4), (1,2) ) ); Group( g1, g2, g3, g4 ) gap> CommutatorFactorGroup( s4 ); Group( g1 )
The default group function GroupOps.CommutatorFactorGroup
uses
DerivedSubgroup
(see DerivedSubgroup) and FactorGroup
(see
FactorGroup) in order to compute the commutator factor group.
