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.

A100485 Decimal expansion of: (1) a simple-continued-fraction-like nesting in which all "partial quotients" are Khinchin's constant (A002210), or, equivalently, (2) the positive solution p of the polynomial p^2 - Khinchin*p - 1 = 0.
