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.

A322342 Expansion of e.g.f. 1/(1 - log(1 + x)/(1 - log(1 + x)^2/(1 - log(1 + x)^3/(1 - ...)))), a continued fraction.
