GroupActionBase

GroupActionBase
is an option to specify a base for a group.
  • A base of a group is a list of points of its domain of action such that the only element in the group fixing them all is the identity.
  • Reordering the points in a base gives a different base.
  • If the list of points given is not a base, Mathematica will add more points until obtaining a base. In particular, GroupActionBase will make Mathematica choose an appropriate base.
