On lattice triangles satisfying $\mathbf{B}(\mathbf{T})=3$ with collinear interior lattice points

Eddy Li, Dana Paquin

A lattice point in ${\mathbb{R}}^2$ is a point $(x,y)$ with $x,y\in \mathbb{Z}$, and a lattice triangle is a triangle whose three vertices are all lattice points. We investigate the i…
