-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.
+6. Instead of storing a basis multiplication matrix, just make
+ product_on_basis() a cached method and manually cache its
+ entries. The cython cached method lookup should be faster than a
+ python-based matrix lookup anyway.
