Counting the number of non-zero coefficients in rows of generalized Pascal triangles
Julien Leroy, Michel Rigo, Manon Stipulanti
This paper is about counting the number of distinct (scattered) subwords occurring in a given word. More precisely, we consider the generalization of the Pascal triangle to binomia…

Generalized Pascal triangle for binomial coefficients of words
Julien Leroy, Michel Rigo, Manon Stipulanti
We introduce a generalization of Pascal triangle based on binomial coefficients of finite words. These coefficients count the number of times a word appears as a subsequence of ano…
