Title: Relations among partitions (III): Some structures with three or four partitions

Abstract:

If we insist that all the pairwise relations among the partitions are either orthogonality or balance (in both directions) or adjusted orthogonality with respect to a third partition, then we obtain interesting structures such as Youden squares, Youden rectangles and triple arrays.
