Stabilizer of a set of points #17621

Closed 6bdad4c1-1e26-4f2f-a442-a01a2292c181 closed 9 years ago

6bdad4c1-1e26-4f2f-a442-a01a2292c181 commented 9 years ago

This branch exposes GAP's feature of computing the stabilizer of a set of points. Right now, Sage only know how to compute the stabilizer of a point.

;-)

sage: G.stabilizer(['a'],"OnMonkeys")

Note that there are other interesting actions available from GAP

Yo!

;-)

sage: G.stabilizer(['a'],"OnMonkeys")

There are no rules (yet) about this kind of things :-P

Note that there are other interesting actions available from GAP

  • OnTuples (for stabilizers, these are simply intersection of action on points)
  • OnSetsSets
  • OnSetsDisjointSets

True. To be honest, I did not want to generalize the code from .orbits (which handles all cases) for only two functions. But then, if a third one needs that, you know... :-P
