Presentation

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

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

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