We have lots of challenges related to the OEIS (Online Encyclopedia of Integer Sequences).
Challenges that are integrated with the OEIS
Challenges that are about producing a sequence from the OEIS
This is just a fraction of the number of challenges we actually have on the subject. For example, this search shows 75 questions with "OEIS" somewhere in the body.
Should we add a tag for this? I see only two potential downsides:
It's a little bit of a meta-tag. Can you be an expert in the OEIS? To be fair, most of our tags that aren't a winning criteria are a little bit meta.
It doesn't add a whole lot on top of the already existing sequence tag. Maybe it should be a synonym instead?
What does meta think? Could this tag contribute anything useful?
