{wiki=Hafner–Sarnak–McCurley_constant}
The Hafner–Sarnak–McCurley constant, often denoted as \\( C \\), is a mathematical constant that arises in number theory, specifically in the context of the distribution of prime numbers, particularly in relation to the number of primes in certain arithmetic sequences. More specifically, it relates to the asymptotic density of prime gaps and primes in certain modular classes.
