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.

Formula

a(n) = b(2^n), where b is A075952, the binary lexicode, d=12.
b(n) = XOR(a(i)) for all i where the i-th bit is set in n.
