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

Polycyclic presentation:
