TableauShape from StandardTableau ​

The shape of a standard tableau: its row lengths.

StandardTableau → IntegerPartitionsurjection

Lossy: the entries are forgotten, so it is not a constructor overload.

Called as CombinatorialMap(x, "TableauShape"). The head's page has its examples.

Each element of StandardTableau at a size, and its image, applied in your browser; sizes past 6 are not offered.

Properties

Transport a statistic

Pick a statistic on IntegerPartition. Its distribution over the images of StandardTableau at each size is computed, and compared with the 25 statistics on StandardTableau: those that share it are the ones the map sends it to, as far as the sizes computed show.
