Presentation

minimal degree	μ(G) = 24
transitive degree	μ_t(G) = 128

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

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