Presentation

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

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

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