Text Formatting ⇒ attempting to get \Box

[diruptivetechnology]

I can get circle and triangle - but I am unable to get \Box, any ideas?

$\Box$ [$L_{\beta}$] $\triangle$ [$L_{\beta'}$] $\bigcirc$ [$L_{\alpha}$]

Hi

I want to get a box displayed within the $ $ symbols. I find that I can get the triangles and circles with $\triangle$ but $\Box$ does not work. I cannot figure out why this may be so when the \Box is labelled along with the \triangle symbol in most user guides. I wonder what is causing this?

The/op I get is confusingly:

! Missing number, treated as zero.

I get symbols from here:

Hi,

but I am unable to get \Box

load the package amssymb or latexsym. For example:

Code: Select all

\documentclass{article}
\usepackage{amssymb}
\begin{document}
$\Box$
\end{document}

Next time please provide more information, for instance which packages you're already using.
