Presentation

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

A minimal faithful permutation representation — 4 generators on 24 points:

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