Presentation

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

A minimal faithful permutation representation — 3 generators on 24 points:

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

Polycyclic presentation:
