Presentation

minimal degreeμ(G) = 24
transitive degreeμt(G) = 64

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

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

Polycyclic presentation:
