Presentation

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

A minimal faithful permutation representation — 5 generators on 24 points:

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