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