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.

Left border = mu(n), A008683.
Right border = A036989, (1, 2, 1, 3, 1, 2, 2, 4, 1, 2, ...) = the inverse Moebius transform (A051731) of the Thue-Morse sequence, offset 1: (1, 1, 0, 1, 0, 0, 1, ...).
Row sums = the Thue-Morse sequence starting with "1".

Examples

			First few rows of the triangle:
