Presentation

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

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

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