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.

A195064 Numbers n such that BCR(n) is not greater than n, where BCR = binary-complement-and-reverse = A036044.
