RFD discussion: November 2018–January 2019[edit]

The following information has failed Wiktionary's deletion process (permalink).

It should not be re-entered without careful consideration.


Suffix entry disguised as a noun entry — but I would think something like 4-holed torus is better regarded as 4-holed + torus and not by suffixing -holed torus as a unit. (One way around this might be to have an entry for n-holed torus or some such; we do have n-dimensional, even though the n is a fairly arbitrary mathematical variable and could really be any letter.)

I believe that the creator's comment is referring to a topological distinction between "hole" like the hole through the middle of a tyre, and "hole" like a hole that would puncture the tyre, the "hole" in "-holed torus" being of the former type. I don't think this entry is the way to do it though. If it is thought necessary to explain this distinction, I suppose it should go at hole. Mihia (talk) 15:11, 22 November 2018 (UTC)Reply
All my socks have holes. That is quite convenient. I use them to put my feet through when putting on socks. The torus holes are more like the holes in Swiss cheese. We are not a topology textbook and if we try to be pedantically precise we are not likely to get all subtleties right. Like the current definition of torus: “A topological space which is a product of two circles.” That only makes sense if a circle is a topological space; however, none of the sixteen senses supplied at circle define a topological space. Also, with that definition, a 2-holed torus is not a torus.  --Lambiam 18:56, 22 November 2018 (UTC)Reply
