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