Presentation

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

A minimal faithful permutation representation — 7 generators on 24 points:

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