Year of OEIS

In 2021, I sampled the vast breadth of the OEIS every day 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 sequence I contributed to was A030078 (Cubes of primes), starting 8, 27, ... .

Likewise, on Jul 13, I contributed to A048375 (Numbers whose square is a concatenation of two nonzero squares), which starts 7, 13, ... due to 49 and 169.

I did this for each day of 2021 and thus called the project Year of OEIS. The complete project encompassed 1015 sequences over 365 days, as summarized below.

Notes

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

Thank You

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.
