How do I strike out indices?

Question

I want to strike out the superscripts and subscripts for an expression like $$\Gamma^{\lambda}_{\mu\nu}$$

I tried the ulem package:

\usepackage[normalem]{ulem} 
\sout{Hello World}

and the soul package

\usepackage{soul}
\st{Hello World}

But neither of worked.

My Question

How do I strike out indices?

Answer 1

The solution is mentioned in Strikeout in math mode

\documentclass{article}
\usepackage{cancel}

\newcommand\hcancel[1]{\setbox0=\hbox{$#1$}%
\rlap{\raisebox{.45\ht0}{\rule{\wd0}{1pt}}}#1} 

\begin{document}

\[
  \Gamma^{\hcancel{\lambda}}_{\hcancel{\mu\nu}}
\]

\end{document}
