[Tex/LaTex] Symbol for contraction / interior product

Question

How to make the symbols for interior product (a.k.a. contraction)? The best I've been able to come up with is \mathrel{\llcorner} (or \lrcorner). Any other suggestions?

Answer 1

MnSymbol package has \invneg symbol, which is most likely what you're looking for. Hope this helps.

\documentclass{article}
\usepackage{mnsymbol}

\begin{document}
\[\invneg\]
\end{document}
