Question: Write down the Lorentz transformation rule for an arbitrary ((3,2)) tensor (A^{mu u ho}{ }_{sigma tau}). Hence show that any double contraction of this tensor

Write down the Lorentz transformation rule for an arbitrary $(3,2)$ tensor $A^{\mu u ho}{ }_{\sigma \tau}$. Hence show that any double contraction of this tensor leads to a contravariant vector, i.e., to a $(1,0)$ tensor.
