Presentation

minimal degreeμ(G) = 24
transitive degreeμt(G) = 128

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

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

Polycyclic presentation:
