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.

A336850 a(n) = gcd(A003961(n), sigma(A003961(n))), where A003961 is the prime shift towards larger primes.
