Presentation

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

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

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

Polycyclic presentation:
