Presentation

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

A minimal faithful permutation representation — 4 generators on 24 points:

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