Presentation

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

A minimal faithful permutation representation — 5 generators on 24 points:

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