Presentation

minimal degreeμ(G) = 24
transitive degreeμt(G) = 32

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

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

Polycyclic presentation:
