Presentation

minimal degreeμ(G) = 16
transitive degreeμt(G) = 32

A minimal faithful permutation representation — 3 generators on 16 points:

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

Polycyclic presentation:

2^8|a^2=f,b^2=g,b^a=bd,c^a=ce,d^a=dg,e^a=eh,f^b=fg,f^c=fh
