Presentation

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

A minimal faithful permutation representation — 4 generators on 24 points:

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

Polycyclic presentation:
