COMMENTS
The odd-order of a polyomino is defined as the minimum odd number of congruent copies required to tile a rectangle. The odd-order is undefined if the polyomino cannot tile a rectangle with an odd number of congruent copies. No example of a non-rectangular polyomino is known for which odd-order = order.
