Webthree packings of interest. In the Z2 packing the spheres are centered at every point in the plane whose coordinates are integers; in the D2 packing the spheres are centered at alternating points of the Z2 packing, in checkerboard fashion. If the coordinate axes of the Z2 packing are rescaled and rotated 45 degrees, the result is the D2 packing.
