TransposePartition from IntegerPartition ​

The conjugate partition: column i of the Ferrers diagram becomes row i.

IntegerPartition → IntegerPartitioninvolution

Entry i of the result counts the parts that are at least i, so it is its own inverse and swaps the number of parts with the largest part. Combinatorica's TransposePartition; FindStat's Mp00044, "conjugate". Wolfram's Conjugate is the complex conjugate, not this map.

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

Each element of IntegerPartition at a size, and its image, applied in your browser; sizes past 7 are not offered.

Properties

Transport a statistic

Pick a statistic on IntegerPartition. Its distribution over the images of IntegerPartition at each size is computed, and compared with the 165 statistics on IntegerPartition: those that share it are the ones the map sends it to, as far as the sizes computed show.
