Parking functions and Haglund--Loehr data
  A parking function is a sequence of N nonnegative integers majorated by a permutation of the set {0, ..., N-1}. We provide a way to encode parking functions by data suggested by J.Haglund and N.Loehr. This coding is compared with another one proposed earlier by M.Shapiro and the author.
