Presentation

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

A minimal faithful permutation representation — 3 generators on 24 points:

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