# Inverse tensor with indices

I'm trying to write an inverse tensor with mixed indices, meaning I want both a {-1} and a {\lambda} in the superscript - but ideally not at the same level/size, since they are different notations. Double superscripts aren't allowed, so I tried writing

\tensor{\Lambda^{-1}}{^\lambda_\mu}


using the tensor package, but this wasn't allowed either. Any suggestions for how to get round this?

• What exactly keeps you from doing \tensor{\Lambda^{-1^{\lambda_\mu}}} (untested)? – Timm Mar 16 '17 at 11:43
• It shows: Error: Sub/Superscript items out of order... I don't know how to get around double superscripts not being allowed. – wheremydoublesubscripts Mar 16 '17 at 14:55
• Sounds like a problem due to tensor. If you could post a complete, minimal example, we might be able to help more. Otherwise try the superscript outside of tensor, \tensor{\Lambda}^{-1^{\lambda_mu}}. The usual math mode can handle multiple superscripts. – Timm Mar 16 '17 at 15:36
