Presentation

minimal degreeμ(G) = 24
transitive degreeμt(G) = 256

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

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

Polycyclic presentation:
