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