Presentation

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

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

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

Polycyclic presentation:
