Presentation

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

A minimal faithful permutation representation — 4 generators on 24 points:

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