WebMar 1, 1990 · THEOREM 1.1. The triangular region TN in the hexagonal lattice can be tiled by congruent copies of the triangular the T, if and only if N = 0, 2, 9, or 11 (mod 12). THEOREM 1.2. It is impossible to tile the triangular region TN in the hexagonal lattice with congruent copies of the three-in-line tile L3. Webturns out that some of these problems can be reformulated as problems in combinatorial group theory. For instance, a necessary condition for a region to be tileable is that a certain element (determined by the boundary of the region) is equal to the identity in a certain group deﬁned by generators and relations (both are determined by the tiles). circlechange
