Presentation

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

A minimal faithful permutation representation — 3 generators on 25 points:

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

Polycyclic presentation:

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