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.

A100845 a(n) = L(P(n)), where P = A000041 (partition numbers) and L = A000032 (Lucas numbers).
