Lattice word
Appearance
In mathematics, a lattice word (or lattice permutation) is a sequence of integers such that in every initial part of the sequence any number i occurs at least as often as the number i + 1. A reverse lattice word, or Yamanouchi word, is a sequence whose reversal is a lattice word.
