# How do you make this symbol in math mode? [duplicate]

This question is as simple as it gets. There's a symbol used for certain polynomials in my area of expertise that I'm completely unfamiliar with, and I'm not sure how to look up the code for the symbol, so I figured I'd ask here.

With detexify, I immediately found it:

\usepackage{amssymb}

\mathfrak{S}

\documentclass{article}
\usepackage{amssymb}

\begin{document}
$\mathfrak{S}$
\end{document}


• Thanks. I guess if you open your mind it kind of looks like an S. I've seen mathfrak used before but only for a few letters. – Matt Samuel Oct 28 '18 at 18:41
• @MattSamuel I'm sorry if I hurt you. I just wanted to indicate an online way to solve this kind of problem. – AndréC Oct 28 '18 at 18:44
