Presentation

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

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

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