Presentation

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

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

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

Polycyclic presentation:

2^9|a^2=e,b^2=f,c^2=e,e^2=h,b^a=bd,c^a=ch,f^a=fg,d^b=dg,g^b=gi,f^d=fi
