Presentation

minimal degree	μ(G) = 24
transitive degree	μ_t(G) = 128

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

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