Presentation

minimal degreeμ(G) = 24
transitive degreeμt(G) = 256

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

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

Polycyclic presentation:
