Redmond–Sun conjecture

In mathematics, the Redmond–Sun conjecture, raised by Stephen Redmond and Zhi-Wei Sun in 2006, states that every interval [x m, y n] with x, y, m, n ∈ {2, 3, 4, ...} contains primes with only finitely many exceptions. Namely, those exceptional intervals [x m, y n] are as follows:

[2^3,\,3^2],\ [5^2,\,3^3],\ [2^5,\,6^2],\ [11^2,\,5^3],\ [3^7,\,13^3],
[5^5,\,56^2],\ [181^2,\,2^{15}],\ [43^3,\,282^2],\ [46^3,\,312^2],\ [22434^2,\,55^5].

The conjecture has been verified for intervals [x m, y n] below 1012. It includes Catalan's conjecture and Legendre's conjecture as special cases. Also, it is related to the abc conjecture as suggested by Carl Pomerance.
