Presentation

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

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

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