+A. Add tests for orthogonality in the Peirce decomposition.
+
+B. Add support for a symmetric positive-definite bilinear form in
+ the JordanSpinEJA.
+
1. Add CartesianProductEJA.
2. Check the axioms in the constructor when check != False?
4. Implement the octonion simple EJA.
-5. Factor out the Jordan axiom and norm tests once all of the
- algebras pass.
+5. Factor out the unit-norm basis (and operator symmetry) tests once
+ all of the algebras pass.
+
+6. Can we make the minimal and characteristic polynomial tests work
+ for trivial algebras, too? Then we wouldn't need the "nontrivial"
+ argument to random_eja().
