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

Polycyclic presentation:

2^6,7|a^2=f,b^2=e,c^2=d,b^a=be,g^a=g^6,c^b=cf
