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

Polycyclic presentation:
