Presentation

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

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

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