Chapter 13.3, Problem 76E

Hexagonal circle packing The German mathematician Gauss proved that the densest way to pack circles with the same radius in the plane is to place the centers of the circles on a hexagonal grid (see figure). Some molecular structures use this packing or its three-dimensional analog. Assume all circles have a radius of 1 and let rij be the vector that extends from the center of circle i to the center of circle j, for i, j = 0, 1, …, 6.
