Presentation

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

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

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