Presentation

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

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

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