-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().
+5. Compute the scalar in the general natural_inner_product() for
+ matrices, so no overrides are necessary.
+
+6. The main EJA element constructor is happy to convert between
+ e.g. HadamardEJA(3) and JordanSpinEJA(3).
+
+7. Figure out if CombinatorialFreeModule's use of IndexedGenerators
+ can be used to replace the matrix_basis().
+
+8. Move the "field" argument to a keyword after basis, jp, and ip.
+
+9. Add back the check_field=False and check_axioms=False parameters
+ for the EJAs we've constructed ourselves. We can probably pass
+ the value of "check_axioms" to <whatever>.span_of_basis() to skip
+ the linear-independence check.
