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.

A371329 E.g.f. satisfies A(x) = (exp(x/(1 - A(x))) - 1)/(1 - A(x)).
