-4. Can we hit "x" with the deortho matrix and delegate to the
-   _rational_algebra to speed up minimal_polynomial?
-
-5. In CartesianProductEJA we already know the multiplication table and
-   inner product matrix. Refactor things until it's no longer
-   necessary to duplicate that work.
+4. Conjecture: if x = (x1,x2), then det(x) = det(x1)det(x2).
