Presentation

minimal degreeμ(G) = 16
transitive degreeμt(G) = 64

A minimal faithful permutation representation — 5 generators on 16 points:

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

Polycyclic presentation:

2^8|e^2=f,g^2=h,b^a=bf,c^a=cg,e^a=ef,g^a=gh,c^b=ch,d^b=df,g^c=gh
