@MartinSleziak Regarding your edit summary here, I'm just curious: what was the action that bumped this question before your edit? Asking purely out of curiosity :)

Also, since the post is anyway being edited, it might be alright to also place the math within dollar symbols.

Well, it seems that it was bumped most recently in June: data.stackexchange.com/mathoverflow/query/1253327/…

in Boulevard of Broken Links, 10 hours ago, by The Amplitwist

@MartinSleziak I was able to find working links for two links in this post that had Wayback Machine snapshots, so in addition to replacing those links, I also replaced the broken link to wwwhomes.uni-bielefeld.de with the DOI link mentioned in your comment.

@TheAmplitwist I saw your message (the one I copied above) saying that you edited the answer - so I checked whether there are other things to edit.

I did not notice that the edit was still pending.

In fact, I should have written: June 2022.

Or maybe - are there delted answers?

@MartinSleziak Ahh. I thought it could have been due to the phrasing of my message, but I didn't want to assume (especially since I don't have enough reputation to view deleted posts).

SEDE: data.stackexchange.com/mathoverflow/query/1479912/… and data.stackexchange.com/mathoverflow/query/1616185/…

SEDE returns nothing (it was last update on September 17). I do not see anything in the Charcoal, either.

It makes me wonder what brought me to that question - after all I left there a comment not too long ago:

The link to Wall's paper now seems to be dead and I did not find it in the Wayback Machine either. After searching a bit, I only found paywalled versions - DOI: 10.1098/rspa.1984.0012, JSTOR. — Martin Sleziak Sep 1 at 5:58

specific-question Can the sphere be partitioned into small congruent cells? Recently bumped by an edit, no top-level tag. Perhaps mg.metric-geometry would be suitable?

Q: Can the sphere be partitioned into small congruent cells?

On the unit $2$-sphere ${\mathbb S}^2$ furnished with the geodesic distance, a subset homeomorphic to a planar disk is called a cell. A finite family of cells is a tiling if their interiors are mutually disjoint and their union is the whole sphere. My main question is: (1) Can the sphere be tile...

@MartinSleziak Yes, that seems appropriate to me.

I have added the tag.

It's a bit unfortunate that the edit on the answer and now my retag detract from the new answer - if somebody clicks on the last activity, they will get the part which was most recently edited.

But that's how the software works - and this was the case already before the retag. (Since the other answer was edited.)

@MartinSleziak Luckily, the question has been bumped again with a new answer.
