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. (Wikipedia).

Kate Jones - A Periodic Table of Polyform Puzzles - CoM Mar 2021
Kate Jones defines, illustrates and describes 12 different types of polyform puzzles, in quaint rhyming couplets of verse, showing the mathematical progression from the singularity to open-ended growth. Polyominoes, polyiamonds, polyhexes, polytans, polyrounds, polyhops, polybends, polyoct

James Propp - Conjectural Enumerations of Trimer Covers of Finite Subgraphs of the Triangular (...)
The work of Conway and Lagarias applying combinatorial group theory to packing problems suggests what we might mean by “domain-wall boundary conditions” for the trimer model on the infinite triangular lattice in which the permitted trimers are triangle trimers and three-in-a-line trimers.
