-A. Add tests for orthogonality in the Peirce decomposition.
-
1. Add CartesianProductEJA.
2. Check the axioms in the constructor when check != False?
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().
