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

Polycyclic presentation:

2^6,7|a^2=ef,b^2=e,d^2=f,b^a=be,c^a=cd,d^a=df,g^a=g^6,d^c=df
