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.

A307635 a(0)=1; thereafter a(n) = largest number that can be obtained by applying "Choix de Bruxelles (version 2)" (see A323460) to a(n-1).
