Query: Universal Counting of Lattice Points in Polytopes   Given a lattice polytope $P$ (with underlying lattice $\lo$), the universal
counting function $\uu_P(\lo')=|P\cap \lo'|$ is defined on all lattices $\lo'$
containing $\lo$. Motivated by questions concerning lattice polytopes and the
Ehrhart polynomial, we study the equation $\uu_P=\uu_Q$.
