Presentation

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

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

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