(a) An FSGG tiling with symmetry . Notice that two edges are common to adjacent tiles, giving edge decorations composed of kites with a single interior edge. (b) The dual tiling of (a), composed of kites and stars. Edges of adjacent stars sharing two vertices are necessarily kinked to accommodate the interstitial elongated kite-shaped faces dual to the kites of (a). Those (vertex-free) edges make the h-net a multigraph. |
