Query: Clean Lattice Tetrahedra   A clean lattice tetrahedron is a non-degenerate tetrahedron with the property
that the only lattice points on its boundary are its vertices. We present some
new proofs of old results and some new results on clean lattice tetrahedra,
with an emphasis on counting the number of its interior lattice points and on
computing its lattice width.
