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