Paywalled article, but I’m assuming it’s talking about the OEIS located here [0]. Such a cool resource, especially if you are trying to calculate S-boxes[1], or a lot of digits of an irrational number, or Bernoulli numbers or something. The links section for each sequence is super useful for initial research.

Past discussion : https://news.ycombinator.com/item?id=26848517

Am I right in remembering that at one point the OEIS ran on a single machine that Neil Sloane ran himself?

Personally, I used to use the database for counts of graphs (labelled vs unlablelled) and chemicals. Very useful and clear single-purpose tool.

I've solved many combinorica-ish problems by extracting a sequence from a numeric solution and then using OEIS to find generating formulas then figuring out which one was the right one.

That analogy about the FBI fingerprint database is one of the most tortured metaphors I've ever heard.

interesting because in my experience Chat GPT has severe problems "understanding" OEIS so i wonder if it could solve the problems the way you did?

I think the Neil Sloane Numberphile episodes are amongst my favourites (along with Cliff Stoll of course) and it's amazing that such a hobby project can become so useful. I think the appeal of his videos is that he introduces sequences as a type of game, draws you in and then later on, the interesting questions are introduced.
