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.
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.
