Presentation

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

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

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

Polycyclic presentation:
