Presentation

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

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

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