Presentation

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

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

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

Polycyclic presentation:
