Presentation

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

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

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

Polycyclic presentation:
