The symbol I'm looking for appears in maths when the closure of an open set is contained in a bigger set; it's like two \subset
, but doesn't look like \Subset
. It's similar to \ll
. How can I typeset that symbol?
Some code showing the different symbols discussed above:
\documentclass{article}
\usepackage{amssymb}
\begin{document}
\ttfamily
\begin{tabular}{ll}
\string\subset & $\subset$ \\
\string\Subset & $\Subset$ \\
\string\ll & $\ll$ \\
\end{tabular}
\end{document}
