Presentation

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

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

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