-1. Add CartesianProductEJA.
+1. Add references and start citing them.
 
-2. Add references and start citing them.
+2. Profile (and fix?) any remaining slow operations.
 
-3. Implement the octonion simple EJA.
+3. When we take a Cartesian product involving a trivial algebra, we
+   could easily cache the identity and charpoly coefficients using
+   the nontrivial factor. On the other hand, it's nice that we can
+   test out some alternate code paths...
 
-4. Factor out the unit-norm basis (and operator symmetry) tests once
-   all of the algebras pass.
-
-5. Override inner_product(), _max_test_case_size(), et cetera in
-   DirectSumEJA.
-
-6. Switch to QQ in *all* algebras for _charpoly_coefficients().
+4. Can we hit "x" with the deortho matrix and delegate to the
+   _rational_algebra to speed up minimal_polynomial?
