Presentation

minimal degreeμ(G) = 23
transitive degreeμt(G) = 112

A minimal faithful permutation representation — 2 generators on 23 points:

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

Polycyclic presentation:

2^5,7|a^2=c,b^2=d,c^2=e,d^2=e,b^a=bd,d^a=de,f^a=f^6
