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