# H Heptomino Compatibility

## Introduction

The *H heptomino* is a polyomino made of seven squares
arranged like a capital H.
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 H
heptomino and other polyominoes.
If you find a smaller solution or solve an unsolved case,
please let me know.

The tromino, tetromino, and pentomino cases
were solved by Giovanni Resta
and can be seen at his monumental website
Polypolyominoes.
