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.

A357349 E.g.f. satisfies A(x) = log(1 + x * exp(A(x))) * exp(A(x)).
