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

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

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