[tex]\sigma\wedge\omega\equiv\frac{1}{2!}(\sigma\otimes\omega-\omega\otimes\sigma)[/tex]

or do some leave off the 1/2!? I'm reading a book in which it appears so far that the author is using simply [tex]\sigma\wedge\omega\equiv\sigma\otimes\omega-\omega\otimes\sigma[/tex] , but I'm not sure if he meant to or just made a mistake.
