Presentation

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

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

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