Presentation

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

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

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