Presentation

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

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

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