Presentation

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

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

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