Presentation

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

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

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