The Polycirculant Conjecture for elusive permutation groups

From papers

Let GG be a finite transitive permutation group. Call GG elusive if it contains no derangements of prime order. The 22-closure of GG on its permutation domain is the largest subgroup of the symmetric group on that domain having the same orbits on ordered pairs as GG; GG is 22-closed if it equals its 22-closure. Polycirculant Conjecture. There are no 22-closed elusive groups. This is a longstanding open problem in algebraic graph theory, with various partial results known.
