duplicate Product of connected spaces - Proof (target linked in comments but my vote expired)

Here's an interesting "failed audit" I just did, Close Review, and the underlying Q [What is the algorithm to add 2 binary with boolean operations? [closed]](math.stackexchange.com/questions/1207206/…). The OP has actually added significant explanation, by way of an example, by editing 11 hours after the original post, but that was 3 hours after it had been put "on hold".

I say the Question is interesting because it seems at first glance to ask for something impossible, and one of the two Answers covers that aspect quite well: addition is not a boolean operation so it cannot expressed merely as a combination of boolean (word-size) operations. However the other Answer points out the possibility of doing this IF the boolean operations are carried out bit-by-bit.

Anyway my suggestion is to reopen with whatever edits are deemed essential to get it out of the Review Audit queue.

@hardmath Only "known-bad" questions are picked as audits. I don't know the precise requirements, but since the question was upvoted today (cf. timeline, I assume it was you), it might be enough to make the post leave the pool of audit questions.

Anyway, I don't understand the question (I didn't put in much effort, TBH, if at least there was some coherent formatting...). If you have edits in mind to make the question clearer, by all means, proceed :)

@2mkgz It's a bit weird, but it seems that this deleted user is one of the owners of this room... Is this normal?

@NajibIdrissi: Okay, I'll turn my hand to it.

@NajibIdrissi Yes, "normal"... the room is very old, and the user who created it left the site a long time ago. Deleted main account... but the chat accounts remain unless deleted separately. So the room sat without an owner for a long time.

@NajibIdrissi One is about product of two spaces; the other is about an arbitrary product, and the question is specifically how to deal with an infinite product when the result is known for finite product.

@2mkgz Oh, you're right. I should have paid more attention. (okay about room ownership)

I had found that one earlier, but I did notice it was about arbitrary products.

So these two 1, 2 are duplicate, but I'm not sure which should be closed as a duplicate of which (or if a merge is to be considered).

The answer to #1 looks more self-contained to me.

undelete math.stackexchange.com/questions/1221481/…

It was a poor question, but the OP now asked it in a more sensible form: math.stackexchange.com/questions/1256248/…

So, some sort of editing/merge thing can be used to sort things out if the first version is undeleted.

@2mkgz You want zhw.'s answer at the new version, right?

@DanielFischer Yes, that would be good.

I guess it's going to be a quick undelete-dupe-close-merge-delete then. 'coz dat anser is good.

unsure Does Are there examples of mathematical problems proven by abduction? contain a mathematical question?

@2mkgz I've also edited the new one a bit into shape, but since I'm not good at improving other people's wordings, it's still a little clumsy. Take a look whether you quickly see a smoother formulation here or there.

@2mkgz I thought "abduction" is what the aliens do. Never guessed there was something called "abductive reasoning".
