Query: The local optimality of the double lattice packing   This paper introduces a technique for proving the local optimality of packing
configurations. Applying this technique to a general convex polygon, we prove
that the construction of the optimal double lattice packing by Kuperberg and
Kuperberg is also locally optimal in the full space of packings.
