Presentation

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

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

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