Levi-Civita symbol
... The tensor whose components are given by the Levi-Civita symbol (a tensor of covariant rank n) is sometimes called the permutation tensor. It is actually a pseudotensor because under an orthogonal transformation of jacobian determinant −1 (i.e., a rotation composed with a reflection), it gets a -1. ...

... it would make sense to determine the number of each part sold based on the number of models sold in each month. For example, the total number of tubes sold in January would equal the number of tubes for Model A times the number of televisions sold in January and the number of tubes sold for model B ...
