Presentation

minimal degreeμ(G) = 23
transitive degreeμt(G) = 224

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

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

Polycyclic presentation:
