👉 In mathematics, a chott is a type of number that can be expressed as the sum of two or more consecutive integers. For example, 27 is a chott because it can be expressed as the sum of 27 and 30 (since both are multiples of 9). Chotts are commonly used in combinatorics to represent the total number of ways to partition a set into non-empty subsets that have the same number of elements.
