The noncototient is a mathematical concept related to number theory. Specifically, it refers to the integers \( n \) for which the equation \( \phi(m) = n \) has no solution for any integer \( m \). Here, \( \phi(m) \) is the Euler's totient function, which counts the number of positive integers up to \( m \) that are relatively prime to \( m \).
