Presentation

minimal degreeμ(G) = 25
transitive degreeμt(G) = 144

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

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

Polycyclic presentation:

2^5,3^2|a^2=c,c^2=d,d^2=e,f^3=g^2,b^a=be,f^a=f^2g,g^a=g^2
