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.

A075850 Greatest k such that f(k,1) divides f(k,n) where f(k,n) is the k-th term of the sequence: f(1,n)=1, f(2,n)=n, f(k+2,n)=f(k+1,n)+f(k,n).
