摘要
An H-triangle is a triangle with corners in the set of vertices of a tiling of ℝ2 by regular hexagons of unit edge. It is known that any H-triangle with k interior H-points can have at most 3k+7 boundary H-points and can not have 3k+6 boundary H-points. In this note we prove that any H-triangle with exactly k interior H-points can not have 3k boundary H-points for k ≥ 5. © Korean Society for Computational and Applied Mathematics 2015.
