Presentation

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

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

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