Presentation

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

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

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

Polycyclic presentation:
