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.

A369603 S is a "boomerang sequence": adding 9 to each digit of S and following the result with a comma leaves S unchanged.
