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.

A135001 Decimal expansion of e+gamma+Pi+phi, where gamma is the Euler-Mascheroni constant and phi is the golden ratio.
