Although Lothar Collatz is most known for the $3x+1$ problem (the Collatz Conjecture), I don’t think their names should be used interchangeably.

Q: identifying the accumulation points of a set

0k33Kindly bear with me as I am a beginner in this topic. The goal is to identify the accumulation points of the set $\{5^a + 7^b: a, b \in \mathbb Z\}$. My definition of accumulation points is (letting $X$ be a metric space, in this case $\mathbb R$, with distance $d$, in this case, I'm assuming Eu...

The tag appeared on one question - but it was almost immediately removed: chat.stackexchange.com/transcript/3740/2018/9/28
@XanderHenderson It seems a bit similar to the tag . On one hand, having narrow tags might be useful when searching. But if we have too many too specific tag, that does not work well with the system which only allows five tags on a question.

@MartinSleziak Honestly, I find it difficult to imagine a question which asks about accumulation points (or limit points, or cluster points, or any similarly related topic) which does not actually use the word under question. Does tagging really help in such cases?
I've removed the accumulation-points tag where it was added.

Since you've mentioned , that tag also had two short-lived incarnations: data.stackexchange.com/math/query/927958/… data.stackexchange.com/math/query/883845/…
Queries which show also editors who added/removed the tag: data.stackexchange.com/math/query/1105163/… data.stackexchange.com/math/query/1038474/…

@XanderHenderson I see you removed it here: math.stackexchange.com/posts/3517745/revisions There was also this question: math.stackexchange.com/posts/532624/revisions
I certainly do not want to start some kind of editing/retagging war over this. If the tag is added somewhere again, perhaps it would be useful either to notify the tag creator or to bring this up on meta (or both).
 
@MartinSleziak I removed it as part of more substantial edits; I didn't think to look for other instances.
