Mirror image of the neg symbol?

Question

Is there a mirror symbol for the $\neg$ symbol, or a symbol like $\vdash$ without the bottom part of the vertical line? I couldn't find it. Thanks.

If you want something with the exact same proportions, you could rotate the original symbol

\documentclass{article}
\usepackage{graphicx}
\newcommand{\rotatedneg}{\rotatebox[origin=c]{180}{\ensuremath\neg}}
\begin{document}
\[
\neg \rotatedneg \vdash
\]
\end{document}

what about vdash without the bottom part, instead of neg which removes the upper part? – kloop Mar 15 '11 at 01:41

\llcorner from amsmath or \niv from nath, amongst others. Just look in the usual places.
