Presentation

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

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

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