Presentation

minimal degree	μ(G) = 24
transitive degree	μ_t(G) = 128

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

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