I've started f(T) theory but I have a simple question like something that i couldn't see straightforwardly.(adsbygoogle = window.adsbygoogle || []).push({});

In Teleparallel theories one has the torsion scalar:

And if you take the product you should obtain

But there seems to be the terms like

.

How does this one vanish?

because we know that Torsion tensor is not symmetric in first two indices but antisymmetric in the last two indices.
