Presentation

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

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

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