I was looking for a \equiv symbol, but with dots on the bottom, on each side of it. I looked up on the comprehensive LaTeX symbol list and couldn't find it.

I tried to write .\equiv ., but didn't like the result and, unfortunately, I don't know exactly what the symbol stands for, my guess is something topology related.

Below, I leave an image on what the symbol look like, any help would be appreciated.

Thanks!

  • Have you actually seen this "in the wild"? If so, can you give a citation? Jan 27, 2023 at 19:19
  • @barbarabeeton, I can't, I just have the symbol. Basically, a friend of mine sent me a message asking if I knew how to write it.

I guess you want a relation symbol:

\documentclass{article}
\usepackage{amsmath}

\newcommand{\dottedequiv}{\mathrel{.{\equiv}.}}

\begin{document}

$X\dottedequiv Y$

\end{document}

enter image description here

The braces around \equiv make it into an ordinary symbol, so TeX doesn't add space around it, but it will around the whole construction that's declared \mathrel.
