Presentation

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

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

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

Polycyclic presentation:
