Presentation

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

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

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

Polycyclic presentation:
