Collinear Interior Lattice Points in Triangles Satisfying $B(T)\in \{4,5\}$

Jonathan Sakunkoo, Annabella Sakunkoo, Dana Paquin

A positive integer $k$ is called $Bn$-collinear if at least one lattice triangle with $n$ boundary points ($B(T)=n$) and $k$ interior lattice points exists, and every such triangle…
