Presentation

minimal degree	μ(G) = 24
transitive degree	μ_t(G) = 256

A minimal faithful permutation representation — 6 generators on 24 points:

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