Over the complex numbers

The cyclic group of order three, being an Abelian group, has the property that all its irreducible representations are one-dimensional, and all representations are thus completely reducible in terms of one-dimensional representations. There are three irreducible representations, the trivial representation, and two representations sending the generators to the cuberoots of unity, in different orders.

Character table

Let ω be a primitive cuberoot of unity.
