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