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.

A276010 a(0) = 0, for n >= 1, a(n) = A275736(n) OR a(A257684(n)), where OR is given by A003986.
