On Parking Functions and The Tower of Hanoi

Combinatorics 2023-12-13 v1

Abstract

The displacement of a parking function measures the total difference between where cars want to park and where they ultimately park. In this article, we prove that the set of parking functions of length nn with displacement one is in bijection with the set of ideal states in the famous Tower of Hanoi game with n+1n+1 disks and n+1n+1 pegs, both sets being enumerated by the Lah numbers.
