**Georgi "Lie Algebras In..."**

It is a old book, I took it from the library two days ago. And I am ashamed that my instructor did not suggest it during our undergraduate group theory.

The selection of exersices is very good. And CarlB will enjoy the one at the end of first chapter: to show that the natural representation in 3 dimensions of the group of permutations of three elements is reducible, and to write down the resulting 1 dim and 2 dim irreps.
