Presentation

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

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

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