LabelingPermutation from ParkingFunction ​

The labeling of the parking function's support Dyck path: the positions of the entries, smallest entry first and equal entries left to right.

ParkingFunction → Permutation

FindStat's Mp00055, which it titles labelling permutation; Sage's standard_permutation().inverse(). A surjection.

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

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

Properties

Transport a statistic

Pick a statistic on Permutation. Its distribution over the images of ParkingFunction at each size is computed, and compared with the 9 statistics on ParkingFunction: those that share it are the ones the map sends it to, as far as the sizes computed show.

to labelling permutation

Matched by value: our map agrees with FindStat's image on each of the 1200 rows of size at most 6 we can read (0 unread; its table has 1200 rows).

SurjectionGraded mapas FindStat records them, checked by FindStat's contributors.

Returns the labelling of the support Dyck path of the parking function.
