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.

A096523 Solutions to A096520[x]>5, that is in neighborhood with c=2^x center and r=Ceiling[Log[2^x]] more than five[6,7,8,..?] primes occur.
