Presentation

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

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

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

Polycyclic presentation:
