Chiral cube - the generalized Goldberg polyhedra

Chern Chuang discovered that one can generalize the Goldberg polyhedra to those polyhedra consisting of square grids, instead of triangular or hexagonal grids. Accordingly, the following polyhedron can be classified as the generalized Goldberg vector (3,1); while the cuboctahedron and rombicuboctahedron as shown in the previous posts can be classified as (1,1) and (2,0), respectively.
