摘要
We review three methods of counting abelian orbifolds of the form C(3)/Gamma which are toric Calabi-Yau (CY). The methods include the use of 3-tuples to define the action of G on C(3), the counting of triangular toric diagrams and the construction of hexagonal brane tilings. A formula for the partition function that counts these orbifolds is given. Extensions to higher dimensional orbifolds are briefly discussed.
