Presentation

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

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

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