Presentation

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

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

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