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

Polycyclic presentation:

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