Let S4 аct оn the set X = {1,2,3,4} in the usuаl wаy: σ · i = σ(i). Let H denоte the subgrоup H = { e, (12), (13), (23), (123), (132) } of S4. Note that H acts on X as well via the same action as S4. a) Determine the orbits of H acting on X. b) Determine the stabilizer of H acting on 1 ∈ X. c) Determine the stabilizer of H acting on 4 ∈ X.
