Do the matrices $S^{\mu\nu} = \frac{1}{4}[\gamma^\mu, \gamma^\nu]$ have a name?

Do the matrices $S^{\mu\nu}$ defined by

$$S^{\mu\nu} = \frac{1}{4}[\gamma^\mu, \gamma^\nu]$$

have a name ($\gamma^\mu$ are the gamma matrices)? They feel very important to me since they form a representation of the Lorentz algebra, so I would like to know if there's an accepted name for them in the literature. If there's none, what would you name them?

These are the generators of Lorentz transformations, see Peskin and Schroeder, pg. 41. $S^{ij}$ are rotation generators, and $S^{0i}$ are the boost generators.
• @Akoben, you're correct. This answer isn't very useful to me because I already know what the $S^{\mu\nu}$ are, I just want to know if they are commonly referred to by some term. – Koaaala Mar 11 '15 at 13:17
