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.

A117100 Numbers k such that nextprime(3*k) > 3*nextprime(k) and k is composite (if p is prime then nextprime(p) = p).
