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

Polycyclic presentation:

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