Presentation

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

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

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

Polycyclic presentation:
