Presentation

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

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

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