Presentation

minimal degree	μ(G) = 24
transitive degree	μ_t(G) = 128

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

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