Presentation

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

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

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