Presentation

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

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

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