Viro's Construction: 4

Viro's Construction: A Sextic (d=6)

Begin with a regular triangulation P_w of
{(x,y) | 0 <= x,y and x+y <= 6} whose vertices are the lattice points

Reflecting P_w in the axes gives its Newton diagram.

A T-curve depends upon signs

and

placed at the vertices of the triangulation P_w.

Extend the signs to the Newton diagram, reflecting each sign and changing those an odd distance from the reflecting axis.
