Presentation

minimal degreeμ(G) = 24
transitive degreeμt(G) = 128

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

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

Polycyclic presentation:
