Presentation

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

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

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

Polycyclic presentation:
