Presentation

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

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

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