Presentation

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

A minimal faithful permutation representation — 3 generators on 24 points:

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