Editing Young tableau (section)

=== Variations ===

There are several variations of this definition: for example, in a row-strict tableau the entries strictly increase along the rows and weakly increase down the columns. Also, tableaux with ''decreasing'' entries have been considered, notably, in the theory of [[plane partition]]s. There are also generalizations such as domino tableaux or ribbon tableaux, in which several boxes may be grouped together before assigning entries to them.
