The compatibility problem is to find a figure that can be tiled with each of a set of polyforms. Polyomino compatibility has been widely studied since 1992, when Pablo Coll first posed and studied the problem for pentominoes.
Here I show minimal known compatibilities for a single pentomino and a pair of other pentominoes, using at least one copy of each pentomino of the pair.
