Legendre's constant

Legendre's constant, denoted as \(L\), is a constant related to the distribution of prime numbers. It is defined in the context of the function that gives the number of primes less than or equal to a given integer \(n\). In particular, Legendre's constant can be expressed in terms of the prime counting function \(\pi(n)\), which counts the number of primes less than or equal to \(n\).
