Hexahex 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 the minimal known tri-oddities for the 82 hexahexes.
Black hexahexes have no solution; gray ones are unsolved.
Please write if you find a smaller solution or solve an unsolved case.
For smaller polyhexes, see Polyhex Tri-Oddities.
