Created by an anon today. I searched that codepoint using Google and Google Books, and I looked on Wikipedia, but I don't know what it means. Current definition: "Ring in equal to." It should be replaced by a definition about actual usage if applicable, like maybe "Indicates equality in the context X". --Daniel Carrero (talk) 17:51, 15 December 2016 (UTC)

The meaning of the symbol (one meaning, anyway) is explained on page 5 of http://people.cs.uchicago.edu/~razborov/files/free_group.pdf. It is highly technical, and I don't personally understand it. I could copy-paste together a definition like "In combinatorial group theory, denotes graphical (or letter-for-letter) equality", but really we need a mathematician. Mihia (talk) 20:27, 15 December 2016 (UTC)

The other issue is if this definition is widely accepted among group theorists or whether it was just made up for this paper. DTLHS (talk) 20:34, 15 December 2016 (UTC)

Per WT:CFI#Independent, I'm pretty sure we would be satisfied if three separate, independent papers use this symbol. --Daniel Carrero (talk) 20:41, 15 December 2016 (UTC)

This book seems to use the same symbol with the same meaning. From a bit of searching, some other books use other symbols, such as ≡ or ≐. Pinging User:Msh210 and User:Kephir, who I think know more math than I do. —Granger (talk · contribs) 01:30, 16 December 2016 (UTC)

Found another instance in this paper. — justin(r)leung _{{ (t...) | c=› }} 01:51, 16 December 2016 (UTC)

It seems to be used for other things, like in this (relation of delimitation) and this (Boolean equality). On another note, it is often used in kaomoji to represent narrow eyes. — justin(r)leung _{{ (t...) | c=› }} 02:07, 16 December 2016 (UTC)

Have you considered asking Wikipedia:en:WT:MATHEMATICS ? -- 65.94.168.229 05:29, 17 December 2016 (UTC)

Ok. See w:Wikipedia talk:WikiProject Mathematics#Please explain the "ring in equal to" symbol. --Daniel Carrero (talk) 22:26, 22 December 2016 (UTC)

For future reference, that discussion has been archived to w:Wikipedia talk:WikiProject Mathematics/Archive/2016/Dec#Please explain the "ring in equal to" symbol. I have added a definition based on it. —Μετάknowledge^{discuss/deeds} 19:27, 11 May 2017 (UTC)
