Brane Cube Realization of Three-dimensional Nonabelian Orbifolds

We study D-branes on three-dimensional orbifolds ${\bf C}^3/\Gamma$ where $\Gamma$ are finite subgroups of SU(3). The quiver diagram of $\ZnZn \in SU(3)$ can be expressed in three-dimensional form. According to the correspondence between quiver diagrams and brane configurations, we construct a brane configuration for ${\bf C}^3/\ZnZn$ which has essentially three-dimensional structrue. Brane configurations for nonabelian orbifolds $\C^3/\Delta(3n^2)$ and $\C^3/\Delta(6n^2)$ are obtained from that for $\C^3/\ZnZn$ by certain quotienting procedure.
