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.

A118763(a(n)) = A118764(a(n)) = A118765(a(n)) = A118766(a(n)) = a(n).
No more terms less than 10^4. Looking at the pattern mod 9, I conjecture that there will be more terms past 10^8. - Joshua Zucker, May 14 2006
