The second Hardy-Littlewood conjecture, in number theory, concerns the number of primes found in intervals of the positive integers. Along with the related first Hardy-Littlewood conjecture, it was proposed by G. H. Hardy and John Edensor Littlewood in 1923.

Connection to the first Hardy-Littlewood conjecture, first sentence
The statement of the second Hardy-Littlewood conjecture is equivalent to the statement that the number of primes from x + 1 to x + y is always less than or equal to the number of primes from 1 to y.
Connection to the first Hardy-Littlewood conjecture, second sentence
This was proved to be inconsistent with the first Hardy-Littlewood conjecture on prime k-tuples
