Square Enneomino Compatibility
The square enneomino is a polyomino made of nine squares
joined to form a 3×3 square.
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 square
enneomino with other polyominoes.
If you find a smaller solution or solve an unsolved case,
please let me know.
DiVincentis found the two solutions with green squares.

into rectangles in general, see Michael Reid's
