Presentation

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

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

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