Presentation

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

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

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