Polyhex (mathematics)

A tessellation of all 7 free tetrahexes

In recreational mathematics, a polyhex is a polyform with a regular hexagon (or 'hex' for short) as the base form, constructed by joining together 1 or more hexagons. Specific forms are named by their number of hexagons: monohex, dihex, trihex, tetrahex, etc. They were named by David Klarner who investigated them.

Each individual polyhex tile and tessellation polyhexes and can be drawn on a regular hexagonal tiling.
