Presentation

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

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

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

Polycyclic presentation:
