Presentation

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

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

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