Presentation

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

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

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