Presentation

minimal degreeμ(G) = 23
transitive degreeμt(G) = 448

A minimal faithful permutation representation — 3 generators on 23 points:

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

Polycyclic presentation:
