Abstract

We introduce the notions of de Bruijn polyominoes and prismatic polyominoes, which generalize the notions of de Bruijn sequences and arrays. Given a small fixed polyomino pp and a set of colors [n][n], a de Bruijn polyomino for (p,n)(p,n) is a colored fixed polyomino PP with cells colored from [n][n] such that every possible coloring of pp from [n][n] exists as a subset of PP. We call de Bruijn polyominoes for (p,n)(p,n) of minimum size (p,n)(p,n)-prismatic. We discuss for some values of pp and nn the shape of a (p,n)(p,n)-prismatic polyomino PP, the construction of a coloring of PP, and the enumeration of the colorings of PP. We find evidence that the difficulty of these problems may depend on the parity of the size of pp
