Triangular Enneiamond Compatibility
The triangular enneiamond is a polyomino made of nine triangles
joined to form a bigger triangle.
The compatibility problem
is to find a figure that can be tiled with each of a set of polyforms.
Here I show minimal known compatibility figures for the triangular
enneiamond with other polyiamonds.
If you find a smaller solution or solve an unsolved case,
please let me know.
