Presentation

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

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

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