  The vertex distortion of a lattice knot is the supremum of the ratio of the
distance between a pair of vertices along the knot and their distance in the
l1-norm. We show analogous results to those of Gromov, Pardon and
Blair-Campisi-Taylor-Tomova about the distortion of smooth knots hold for
vertex distortion: the vertex distortion of a lattice knot is 1 only if it is
the unknot, and that there are minimal lattice-stick number knot conformations
with arbitrarily high distortion.
