Presentation

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

A minimal faithful permutation representation — 3 generators on 24 points:

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