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.

A159821 Continued fraction for (e*Pi*phi)^2 A131566, where phi = (1 + sqrt(5))/2.
