D-branes on Three-dimensional Nonabelian Orbifolds

We study D-branes on a three complex dimensional nonabelian orbifold ${\bf C}^3/Γ$ with $Γ$ a finite subgroup of SU(3). We present general formulae necessary to obtain quiver diagrams which represent the gauge group and the spectrum of the D-brane worldvolume theory for dihedral-like subgroups $Δ(3n^2)$ and $Δ(6n^2)$. It is found that the quiver diagrams have a similar structure to webs of branes.
