Presentation

minimal degreeμ(G) = 24
transitive degreeμt(G) = 64

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

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

Polycyclic presentation:
