Abstract
Let phi be a self-map of the symmetric group S_Omega acting on a countable set Omega . We show in an elementary fashion that if phi has the property that sigma tau is conjugate to phi (sigma )phi (tau ) for every choice of sigma ,tau in S_Omega , then it is necessarily an automorphism or an antiautomorphism of S_Omega . As a corollary to this result, the so-called 2-local automorphisms of S_Omega are also described.
