Presentation

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

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

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

Polycyclic presentation:
