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