This paper presents and solves a problem related to decomposing 1 into a sum of unit fractions. Decomposition into two terms, composition of two terms, decomposition into three terms, and other methods are used to find ways to maximize the number of unique terms, and a decomposition into 42 terms is demonstrated.
