Presentation

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

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

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