returns the stabilizer subgroup under the action given by the function f.

DetailsDetails

  • The output is a subgroup of group defined by generators, but possibly using different generators.
  • The stabilizer group is also known as the little group or isotropy group.
  • The stabilizer of a list of points is a subgroup of the setwise stabilizer of the same list of points.
  • For permutation groups, the default group action is taken to be PermutationReplace.
