Presentation

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

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

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