Presentation

minimal degree	μ(G) = 24
transitive degree	μ_t(G) = 256

A minimal faithful permutation representation — 5 generators on 24 points:

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