Unit Contact Representations of Grid Subgraphs with Regular Polytopes in 2D and 3DAdditionally, we show that subgraphs of the triangular grid admit a UPCR with cubes, implying that the same holds for each subgraph of an Archimedean grid. Considering further polygons, we construct UPCR with regular 3.-gons of the hexagonal grid and UPCR with regular 4.-gons of the square grid.
