This question already has an answer here:

I want to use the $\pitchfork$ symbol to denote transversal intersection, but when I compile my code, it does not appear. So for example, $\Gamma \pitchfork W$ just comes up like $\Gamma W$. I am using Texmaker.

Would appreciate any help to resolve this issue.

MWE:

\documentclass[10pt]{article}
\usepackage{amsmath}
\usepackage{graphicx}
\usepackage{cite}
\usepackage{authblk}
\pdfoutput=1
\usepackage{amsfonts}
\usepackage{float}
\usepackage{mathtools, cuted}
\usepackage{lipsum, color}
\usepackage[margin=1.8cm]{geometry}
\usepackage{amsthm}

\begin{document}

Consider $\Gamma \pitchfork W$

\end{document}

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

  • Do you have the required packages loaded? Please show a MWE. – TeXnician Apr 20 '17 at 10:05
  • Sorry I am not very experienced with tex. What is MWE? @TeXnician – Alex Apr 20 '17 at 10:07
  • A MWE is a minimal working example, a minimal compilable document reproducing your error, you would post here. – TeXnician Apr 20 '17 at 10:08
  • Will edit my post above @TeXnician – Alex Apr 20 '17 at 10:10
  • I think you'll need package amssymb – TeXnician Apr 20 '17 at 10:22

If you add \usepackage{amssymb} it works (at least for me).

\documentclass[10pt]{article}
\usepackage{amsmath}
\usepackage{amssymb}
\usepackage{graphicx}
\usepackage{cite}
\usepackage{authblk}
\pdfoutput=1
\usepackage{amsfonts}
\usepackage{float}
\usepackage{mathtools, cuted}
\usepackage{lipsum, color}
\usepackage[margin=1.8cm]{geometry}
\usepackage{amsthm}

\begin{document}

Consider $\Gamma \pitchfork W$

\end{docum
