Presentation

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

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

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