Presentation

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

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

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