Octagon graph paper
This pattern is the truncated square tiling: each regular octagon shares its top, bottom and side edges with a neighbor, and the diagonal edges frame small squares turned 45°. It is the classic layout of octagon-and-dot floor tiles.
The spacing sets the width of each octagon across its flat sides. Each octagon borders four octagons and four small squares, which makes the grid a neat alternative to squares and hexes for game boards.
