Presentation

minimal degree	μ(G) = 24
transitive degree	μ_t(G) = 64

A minimal faithful permutation representation — 3 generators on 24 points:

(1,2)(3,5,7,8)(4,6)(9,10,12,18,16,19,23,24,15,20,13,22,14,11,21,17);(1,3)(2,5,6,8)(4,7)(9,11,15,19)(10,16,20,14)(12,18,13,22)(17,21,24,23);(3,7)(5,8)(9,12,16,23,15,13,14,21)(10,17,11,22,20,24,19,18)
