Presentation

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

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

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

Polycyclic presentation:
