"Image of" symbol[edit]

A question on one of our article talk pages referenced this symbol, which I do not recall ever having seen: ⊷

Googling it confirms that the symbol is understood as "image of". But most of the results are not even mathematical; they look like what you might get by searching for the literal words "image of". I considered asking this at the language refdesk for that reason, but it seems to me that this is probably intended as a mathematical symbol of some sort.

Has anyone run across this symbol, or does anyone know how to find genuine uses of it in the wild? --Trovatore (talk) 19:39, 14 November 2017 (UTC)[reply]

I did some looking; it is indeed called the "image of" glyph, it is Unicode U+22B7, and this page has basic unicode information on it. It seems to be part of a block of unicode symbols with similar designs and names, maybe looking for one of those symbols in the same neighborhood can help? The link I gave lets you flip through unicode one at a time; maybe those can help? --Jayron 32 21:08, 14 November 2017 (UTC)[reply]

Thanks, Jayron. That is a useful page. I still haven't managed to find the symbol in the wild with the indicated meaning, but it kind of puts it into context with a bunch of other little-used symbols (and a few that really are used, like "forces"). --Trovatore (talk) 22:29, 14 November 2017 (UTC)[reply]

@Trovatore: That symbol is part of the Mathematical Operators Unicode block. Elsevier includes it in Science Grid B, so there exists a publication that uses it. That's said, it's obscure and I can't find a concrete example. C0617470r (talk) 05:11, 24 November 2017 (UTC)[reply]
