Presentation

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

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

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