[Tex/LaTex] How to write index for levi-civita symbol

Question

I need write (2) on latex, but when i try \epsilon_{\alpha}^{\beta\gamma}, latex shows me (3), somebody knows how to do left that space between index?

Answer 1

This is a tensor, so why not using the tensor package?

\documentclass{article}
\usepackage{amsmath}
\usepackage{tensor}

\newcommand{\levicivita}{}% initialize
\def\levicivita#1#{\tensor#1{\epsilon}}

\begin{document}

\[
\levicivita{_{\alpha\beta\gamma}}
\qquad
\levicivita{_{\alpha}^{\beta\gamma}}
\qquad
\levicivita{^{\beta}_{\alpha\gamma}}
\]

\[
\levicivita*{*^{\beta}_{\alpha\gamma}}
\]

\end{document}
