Presentation

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

A minimal faithful permutation representation — 4 generators on 24 points:

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