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.

A166347 Irregular triangle read by rows of the frequency with which each value v of floor (j^2/p) occurs within A165974 for each prime p, taken over 1 <= j <= p - 1.
