Presentation

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

A minimal faithful permutation representation — 4 generators on 16 points:

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

Polycyclic presentation:

2^8|b^2=g,c^2=g,d^2=g,e^2=g,f^2=h,b^a=be,c^a=cf,d^a=dg,e^a=eg,f^a=fh,d^b=dg,e^b=eg,f^b=fh,e^c=eh,f^c=fh
