After searching the MathsJax tutorial pages, I couldn't find an actual symbol for $\require{cancel} \cancel{\exists}$

The way I have written it <\require{cancel} \cancel{\exists}> is the best I could think of, but it seems ridiculous compared to the simple <\exists> command for $\exists$.

Any suggestions? Thanks!

    $\begingroup$ From the Mathjax quick reference guide: You can use \not to put a slash through almost anything. $\endgroup$ Feb 10, 2023 at 17:54

    $\begingroup$ Maybe the quick reference needs to make this more prominent. $\endgroup$

    $\begingroup$ @TheSimpliFire - I don't know how you resisted answering "$\not \exists$ exists". $\endgroup$

    $\begingroup$ Better yet, $\lnot \exists$: \lnot exist. If your question relates to logic, or the use of quantifiers, and their negation, then the standard notation is \neg \exists, $\neg \exists$ or \lnot \exists $\endgroup$
