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