Presentation

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

A minimal faithful permutation representation — 4 generators on 24 points:

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