Permutation group

Multiply transitive permutation group

A permutation group 𝐺 βŠ†Ξ©! is π‘˜-transitive iff it acts on ordered tuples in Ξ©Pπ‘˜ transitively. group

Classification

  • For π‘˜ β‰₯6, the only π‘˜-transitive groups are S𝑛 with 𝑛 β‰₯π‘˜ and Alt𝑛 with 𝑛 β‰₯π‘˜ +2;
  • The only 5-transitive groups that aren’t 6-transitive are Mathieu group M24, Mathieu group M12, [[Symmetric group|S5]], and [[Alternating group|Alt7]].
