Presentation

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

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

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