# Order of a polyomino

## Definition

"In 1968, David A. Klarner defined the order n of a polyomino P as the minimum number of congruent copies of P that can be assembled (allowing translation, rotation, and reflection) to form a rectangle. For those polyominoes which will not tile any rectangle, the order is undefined."
