Presentation

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

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

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

Polycyclic presentation:

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