Permutation Groups [HB 20]
New Features:
-
A dynamically constructed disjoint cycle form of a permutation may
now be used. E.g., G![{@ 1, 3,..@},{@ 2,
6,..@}, ...] is now the same as G!(1,3,..)(2,6,..)....
Note that Cycle(G![{@ 1, 3,..@},{@ 2,
6, ... @}, ...], 1) will
give {@ 1, 3, ... @}.
-
The function IsConjugate has been extended in the case of
permutation groups to allow the testing of whether a pair of indexed
sets or a pair of multisets of points of G lie in the same
G-orbit.
Bug fixes:
-
Bug fixed in GSet(GrpPerm, SetMulti). This signature
now generates a runtime error. This avoids the potential problem of
things in the same orbit having different multiplicities.
-
Bugs fixed in: DerivedSeries, PCGroup, SolubleQuotient, CompositionFactors, IsSimple, Cycle, CosetAction(GrpAb, GrpAb), Subgroups, NormalSubgroups, MaximalSubgroups.
