Presentation

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

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

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