Presentation

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

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

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