Russ. Math. Surv. 51, No. 2, 333-335 (1996); translation from Usp. Mat. Nauk 51, No. 2, 165-166 (1996).
A word of length \(2k\) in the alphabet \(\{1,2, \dots, k\}\) with (a) each letter of the alphabet occurs twice, and (b) between two successive occurrences of any particular letter there can appear only letters that are strictly greater than it, is called a Gessel-Stanley (GS) permutation. In this paper various bijections between GS-permutations and other combinatorial objects are given.
