Presentation

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

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

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

Polycyclic presentation:
