Presentation

minimal degreeμ(G) = 25
transitive degreeμt(G) = 320

A minimal faithful permutation representation — 2 generators on 25 points:

(1,2,3,5,4)(6,7,8,9);(2,3,4,5)(7,9)(10,11,12,15,13,16,18,21,14,17,19,22,20,23,24,25)

Polycyclic presentation:

2^6,5|a^2=c,b^2=d,c^2=e,e^2=f,b^a=bd,g^a=g^2,g^c=g^4
