Abstract: In [6] and [7] L. Ţâmbulea studied the number of positive integers sequences (s1, s2, ..., s2n+1) with the properties: s1 = s2n+1= 1 and |si - si+1| = 1 for each i between 1 and 2n. In this note we discuss the algorithm to code this sequences by Dyck words and several related problems. Key words and phrases. sequences of integers, Catalan numbers, Dyck words. |
