Presentation

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

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

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