Like most math problems. That's what they are. You can compute asymptotics of the code you create etc. The first problem listed, is equivalent to asking if:$$\binom{9n}{n}\cdot\binom{8n}{n}\cdot\binom{7n}{n}\cdot\binom{6n}{n}\cdot\binom{5n}{n}\cdot\binom{4n}{n}\cdot\binom{3n}{n}\cdot\binom{2n}{n}\cdot (n!)^9+n!+1$$ can be prime. Which is quite the ...

We should keep these problems, because you never know when you have one. Some days ago, user Nikita asked the question Is this contrived sequence eventually periodic?. Innocently enough, they explained that they had built quite a weird sequence $A(n)$, which seemed to have a period, as all residue classes mod $6$ except for one gave the exact same thing. I ...

Proposal: rename quasiperiodic-functions to quasiperiodicity. Reason: posts tagged quasiperiodic-functions may also be tagged quasiperiodicity, but the reverse is not always true (ie. posts on quasiperiodic tiling or oscillations). Because none of these topics get much attention, there should be one tag to cover all of them.

Using Data Explorer (SEDE) you can check how has the number of questions in some given tag evolved over time. Here are two queries, one showing absolute number of questions in the elementary-set-theory, the other one showing percentage of all question which have this tag. The latter is taken from here: A statistical question about statistical questions. ...

My understanding is that most of the time, someone who asks a question on an elementary topic will not be able to name precisely what the relevant tags are. In such cases, it's all up to more senior users to tidy things up. But then not all questions get re-tagged properly because there are too many of them, because not everyone thinks of taking care of ...

Proposal: create tag "inverse-fourier" I think there should be a tag named inverse-fourier which represents mainly the inverse fourier transform. I know there is a tag named fourier-transform but inverse fourier transform is also an important area of research. It has many application too. I want a suitable discussion about that. If everything goes alright, ...

Proposal: rename eulerian-path to euler-trail First off, a walk that traverses every edge of a graph is generally not a path but a trail. Second, when this situation occurs, it is the graph that is described as Eulerian and not the walk (at least IME). While I'm here, I may as well add that the tag is used to discuss Euler circuits (not to be confused ...

Proposal: Remove the tag infinite-dimensional-space This tag was created by the question Are there such things as infinite-dimensional regular polytopes?, which is currently the only question with this tag. I don't see this tag having much utility. Update : The tag has been removed from the question, and should disappear soon.

Proposal: Add the tag grad-curl-div; make gradient, curl and divergence aliases thereof. Edit 2: I've revised the proposal statement to Alexander Gruber's (in my view superior) suggestion in the comments. Implementing this proposal poses some advantages over the status quo: It would (productively) free the > 6k questions about the gradient from the rather ...

Proposal: Hyphenatecrossedproducts. Reason: Hyphenation improves readability, and is standard practice.

I agree that these tags are not needed. For the former I suggest to retag the two questions (the tag then goes automatically away after a day). For the latter we might wait for a few days if the question "survives" or not. If the questions should be deleted the tag would be gone too. For tags that only have a few questions to them, retagging is usually ...
