CentralWeight( g )
CentralWeight returns the central weight of an ag word g, with
respect to the central series used in the combinatorial collector, as
This presumes that g belongs to a parent group for which the combinatorial collector is used. See ChangeCollector for details.
If g is the identity, 0 is returned.
CentralWeight allows records that mimic ag words as
gap> d8 := AgGroup( Subgroup( s4, [ a, c, d ] ) ); Group( g1, g2, g3 ) gap> ChangeCollector( d8, "combinatorial" ); gap> List( d8.generators, CentralWeight ); [ 1, 1, 2 ]
