cp's OEIS Frontend

This is a front-end for the Online Encyclopedia of Integer Sequences, made by Christian Perfect. The idea is to provide OEIS entries in non-ancient HTML, and then to think about how they're presented visually. The source code is on GitHub.

A256471 Numbers n for which there is an equal number of primes in range [prime(n)^2, prime(n)*prime(n+1)] as there are primes in range [prime(n)*prime(n+1), prime(n+1)^2].
