Presentation

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

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

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