# New command for double coset

I defined a new command \doublefaktor to print a double coset of type A\B/C (similar to \faktor which print a quotient A/B) as follows:

\newcommand{\doublefaktor}[3]{ {\textstyle #1}\mkern-8mu\diagdown\mkern-5mu^{\textstyle #2}\mkern-5mu\diagup\mkern-8mu{\textstyle #3} }


(thanks to previous suggestions here) but I would like to have bigger \diagdown and \diagup in the pdf-printing. How can I do?

• \big doesn't take an argument (as in \big{arg.}): it is prefixed to a math delimiter, like in \big( or \big| or \big\{. Mar 16 '20 at 11:46
• Additionally please make your sniplet into a complete example, there are several macros here we do not know the definition of, and thus we cannot test your code without guessing Mar 16 '20 at 11:49
• And that is going to help us how? Provide the code, else others cannot test or help with your problem. Mar 16 '20 at 12:14
• What exactly is it you are trying to do? Do you even know what \big does? Why are you attempting to apply \big to a letter? Perhaps you should start completely over. Explain what the end goal is and then perhaps someone can help you. Mar 16 '20 at 12:24
• Your edit sill not provide MWE (Minimal Working Example, a small but complete document, which reproduce your problem), which would enable simple testing of your problem. Mar 16 '20 at 12:55

A pure guessing:

\documentclass{article}
\usepackage{graphicx}
\usepackage{amssymb}
\newcommand{\doublefaktor}[3]{%
{\textstyle #1}
\mkern-4mu\scalebox{1.5}{$\diagdown$}\mkern-5mu^{\textstyle #2}%
\mkern-4mu\scalebox{1.5}{$\diagup$}\mkern-5mu{\textstyle #3} }

\begin{document}
$\doublefaktor{A}{B}{C}$
\end{document}


Note, above document example is called MWE (Minimal Working Example). It gives after compilation the following result:

• Thank you so much. For future question how can I display a MWE? Mar 16 '20 at 21:21
• @V.Galgano, copy content from your LaTeX editor to question window, than put ` before and after it. That is. Mar 16 '20 at 21:58
