Presentation

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

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

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