Presentation

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

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

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