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