Presentation

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

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

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