Draw the 4-cube Q4 and label each vertex with the minterm in the Boolean variables w, x, y, and z associated with the bit string represented by this vertex. For each literal in these variables, indicate which 3-cube Q3 that is a subgraph of Q4 represents this literal. Indicate which 2-cube Q2 that is a subgraph of Q4 represents the products wz, xy, and y z.
