Presentation

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

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

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

Polycyclic presentation:
