Observe that this example is taken from Examples 1 and 3. The matrix A corre-
sponds to Example 1 and the matrix A to Example 3. See Figure 3 for Example
3 where there are three completely labeled simplices of type I after having been
transformed. In this case there is no completely labeled simplex of type II. The
reader should compare Figure 1 with Figure 3.
