Structural Theory and Classification of 2D Adinkras

Figure 5

Constructing the D Adinkra (b) from two smaller D Adinkras (a) as a product. Note that the dashings are all “consistent” with the smaller Adinkras, except for the right-moving edges on the upper-left “boundary” of the rectangle; these correspond to right-moving edges where the grading corresponding to the first Adinkra has height .
