Presentation

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

A minimal faithful permutation representation — 3 generators on 24 points:

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