Year of OEIS

Year of OEIS

In 2021, I sampled the vast breadth of the OEIS by exploring and contributing -- usually a Python program -- to at least one sequence that started with

MM, DD for each month MM and day DD of the year

For example, on Aug 27, one is A030078 (Cubes of primes), starting 8, 27, ... . Likewise, on Jul 13, A048375 (Numbers whose square is a concatenation of two nonzero squares) starts 7, 13, ... due to 49 and 169.

I called the project, Year of OEIS. It is summarized below.

Notes

There are 1015 sequences above. Some start X, MM, DD where X is another term (e.g., 0). Occasionally, other patterns sneak in, such as a 1, 1, 1, 2, ... on 11/12 and a 1231, ... on 12/31.

This project would not have been possible without the tireless work of the OEIS' editors, especially Michel Marcus, Joerg Arndt, Alois P. Heinz, and N. J. A. Sloane.
