We present a way of tiling the plane with a regular hexagonal network of
defects. The network is stable and follows in consequence of the
three-junctions that appear in a model of two real scalar fields that presents
Z3​ symmetry. The Z3​ symmetry is effective in both the vacuum and defect
sectors, and no supersymmetry is required to build the network.Comment: Revtex, 4 pages, 1 ps figure; version to appear in Phys. Rev. Let
