-0. Add tests for orthogonality in the Peirce decomposition.
+1. Add references and start citing them.
 
-1. Add CartesianProductEJA.
+2. Profile (and fix?) any remaining slow operations.
 
-2. Check the axioms in the constructor when check != False?
+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. Implement the octonion simple EJA.

-5. Factor out the unit-norm basis (and operator symmetry) tests once
-   all of the algebras pass.

-6. Rename the algebra "characteristic polynomial" method to
-   "characteristic polynomial of."
+4. Conjecture: if x = (x1,x2), then det(x) = det(x1)det(x2).
