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.

A075007 a(n) = floor(concatenation of n+5, n+4, n+3, n+2, n+1 and n divided by 6).
