Consider the walk taking an up step for each ascent, and a down step for each descent of the permutation. Then this statistic is the number of steps that begin and end at non-negative height. ----------------------------------------------------------------------------- References: [1] Bernardi, O., Duplantier, B., Nadeau, P.
