Presentation

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