Presentation

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

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

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