Title:
Jordan's Theorem on primitive permutation groups

Abstract:
I will present an elementary proof of a 1872 theorem on finite permutation groups by Jordan.

Jordan's theorem says that the only primitive permutation groups on n letters containing a cycle of prime length p with n-p # 3 are the alternating group A_n and the full symmetric group S_n.
