Presentation

minimal degree	μ(G) = 24
transitive degree	μ_t(G) = 64

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

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