    the nontrivial factor. On the other hand, it's nice that we can
    test out some alternate code paths...
 
-4. Can we hit "x" with the deortho matrix and delegate to the
-   _rational_algebra to speed up minimal_polynomial?
+4. Add dimension bounds on any tests over AA that compute element
+   subalgebras.
 
-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.
+5. The rational_algebra() stuff doesn't really belong in classes that
+   don't derive from RationalBasisEJA or its as-yet-nonexistent
+   element class.
 
-6. Eliminate the matrix_space() override in CartesianProductEJA.
+6. Add special det/trace method overrides for the algebras where we
+   know them? The only reason this might be tricky is because the
+   obvious solution is to subclass EJAElement, but then we might
+   collide with e.g. the Cartesian product element subclass.
