Presentation

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

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

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