Hexagon partitioned into six equilateral triangles. Like squares and equilateral triangles, regular hexagons fit together without any gaps to "tile the plane" (three hexagons meeting at every vertex), and so are useful for constructing tessellations. The cells of a beehive honeycomb are hexagonal for this reason and because the shape makes efficient use of space and building materials. The Voronoi diagram of a regular triangular lattice is the honeycomb tessellation of hexagons. It is not usually considered a triambus, although it is equilateral. The maximal diameter (which corresponds to the long diagonal of the hexagon), "D", is twice the maximal radius
Campaign Hexagon System Campaign Hexagon System Campaign Hexagon System is a supplement for fantasy role-playing games published by Judges Guild in 1977. "Campaign Hexagon System" is a GM's aid: a book of blank hexagon sheets overprinted with larger gray hexes so the GM can integrate wilderness maps of varying scales. It includes tables for generating wilderness terrain. "Campaign Hexagon System" is a booklet of which the main portion is devoted to over 60 blank campaign hex grids. A rectangular hexagonal tessellation of about 1000 small hexes appears on each page, and on this grid is superimposed a large hex representing 5 miles across
