Presentation

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

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

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