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.

Formula

G.f.: 1/(1 - Sum_{k>=2} x^(k^3)).
a(0) = 1; a(n) = Sum_{k=2..n} A010057(k) * a(n-k).
