Presentation

minimal degree	μ(G) = 24
transitive degree	μ_t(G) = 64

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

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