The multi-width tetrahedron counting conjecture. There is a piecewise quasi-polynomial with four components counting lattice tetrahedra of multi-width $(w_1,w_2,w_3)$. There is one…

Let $w_1,w_2$ be the first and second entries of the multi-width of a lattice four-point set in the plane. The number of four-point sets of multi-width $(w_1,w_2)$ is conjectured t…
