I am trying to find a symbol for "less than, equal to, or greater than" similar to this:

I have not been able to find one. If anyone knows of such a command, please let me know.

Thank you

    In similar cases you can use http://detexify.kirelabs.org/classify.html - draw your desired symbol and it tries to recognize it. Your case: \usepackage{ amssymb } \lesseqqgtr :) – uzsolt Dec 03 '18 at 04:44

    What's the use-case? :D – technical_difficulty Dec 03 '18 at 07:22
  • Makes no sense to me as it indicates that there is no relationship between the numerical values. – Peter Wilson Dec 03 '18 at 19:03
  • @PeterWilson mathematical theoreticists will have their use-case for such a hell-born symbol. As a non-mathematician, I don't question their methods. As long as a math's doctor came up with the symbol, I imagine there is indeed a use for it. – thymaro Dec 31 '18 at 22:09
  • @thymaro I'm not a mathematician as my father told me that the UK only needed five and I was not one of them, so I became an engineer. He was happy with answers involving integrals and Greek and Russian letters but I needed numbers. – Peter Wilson Jan 02 '19 at 19:32

    @PeterWilson in a partial order (or preorder), that symbol indicates that there is some order relationship between two elements: one of them is less than or equal to the other, without necessarily knowing which one is which . The negation of that symbol indicates that two elements are unrelated in the order, i.e. that neither is less than or equal to the other. – Stefano Gogioso Jul 18 '21 at 11:59

Here are the possibilities with amssymb:

\documentclass{article}
\usepackage{amssymb}

\begin{document}

\[ A\gtreqqless B, \quad A\lesseqqgtr B\]%
\[ A\gtreqless B\quad A\lesseqgtr B\]%
\[ A\gtrless B\quad A\lessgtr B\]%

\end{document}

Here are two possibilities using \usepackage[T1]{fontenc} or \usepackage{amssymb}:

\documentclass{article}
\usepackage[T1]{fontenc}
\usepackage{amssymb}

\begin{document}
    \centering

    $\theta_{nc}^D < \theta^D$\\
    $\theta_{nc}^D > \theta^D$\\
    $\theta_{nc}^D = \theta^D$\\
    $\theta_{nc}^D \leq \theta^D$\\
    $\theta_{nc}^D \geq \theta^D$\\ 

    $\theta_{nc}^D\lesseqqgtr \theta^D$

\end{document}
