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.

A189225 Entries in a 4-dimensional version of Pascal's triangle: quadrinomial coefficients of (a + b + c + d)^r.
