Presentation

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

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

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