Presentation

minimal degreeμ(G) = 17
transitive degreeμt(G) = 160

A minimal faithful permutation representation — 3 generators on 17 points:

(1,2,4,5,3)(7,9)(10,13,12,11,15,17,14,16);(6,7)(8,9)(10,12,15,14)(11,13,16,17);(2,3)(4,5)(10,11)(12,13)(14,17)(15,16)

Polycyclic presentation:

2^6,5|b^2=f,c^2=df,d^2=f,c^a=cd,d^a=df,g^a=g^4,c^b=ce
