# Multiple Compatibility for Polyominoes

## Introduction

A set of polyforms is *compatible*
if there exists a figure that each of them can tile.
Here are minimal figures that can be tiled by a given number of
*n*-ominoes.
Most are taken from Jorge Luis Mireles's defunct site
**Poly**^{2}ominoes.
If you find a smaller solution or one that can be tiled by more
*n*-ominoes, please write.
For arbitrary sets of three pentominoes, see Livio Zucca's
Triple Pentominoes.
For arbitrary sets of four pentominoes, see
Quadruple Pentominoes.

For other polyforms,
see Multiple Compatibility
for Polyiamonds
and
Multiple Compatibility
for Polyhexes.
