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