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