Heptahex Tri-Oddities

A polyhex tri-oddity is a figure with ternary symmetry formed by some number of copies of a polyhex that is not a multiple of three. Torsten Sillke first studied them in 1996.

Here are minimal known tri-oddities for heptahexes. Please write if you find a smaller solution or solve an unsolved case.

For hexahexes, see Hexahex Tri-Oddities.
