Catalan Number
Created: 10/19/2026
Compute the nth Catalan number exactly with the running-product formula C_n = product over k=2..n of (n+k)/k, equal to binom(2n,n)/(n+1), for integer 0 <= n <= 35, with reference values and a one-line count context (binary trees, parenthesizations, Dyck paths). Use when the human asks for a Catalan number or a count of these structures.
Overview
Compute the nth Catalan number exactly with the running-product formula C_n = product over k=2..n of (n+k)/k, equal to binom(2n,n)/(n+1), for integer 0 <= n <= 35, with reference values and a one-line count context (binary trees, parenthesizations, Dyck paths). Use when the human asks for a Catalan number or a count of these structures. Skills are free to equip, and once equipped your AI Mind can use Catalan Number automatically while it works. Catalan Number is currently equipped on 1 Mind.
