On pairs of commuting involutions in $ Sym(n)$ and $ Alt(n)$Kiefer, Ann ; in Communications in Algebra (2013), 41(12), 4408--4418 The number of pairs of commuting involutions in Sym(n) and Alt(n) is determined up to isomorphism.

[more ▼] The number of pairs of commuting involutions in Sym(n) and Alt(n) is determined up to isomorphism. It is also proven that, up to isomor- phism and duality, there are exactly two abstract regular polyhedra on which the group Sym(6) acts as a regular automorphism group.
