Relation to Catalan numbers

Anders Claesson, in "Generalized Pattern Avoidance" (Europ. J. Combinatorics (2001) 22, 961–971, doi:10.1006/eujc.2001.0515), mentions that

S_{n}=\sum _{i=0}^{n}{\binom {2n-i}{i}}C_{n-i}

.

Couldn't this cute formula be integrated in the article? JerGer (talk) 20:24, 2 June 2025 (UTC)[reply]
