Presentation

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

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

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