Hello, I am trying to define a matrix group generated by matrices over a field which I have defined. At the moment, I am stuck with the the question of how to make the base_ring an instance of CommutativeRing? In particular, I get that the __init__ in free_module.pyc asks isinstance(base_ring, commutative_ring.CommutativeRing), which is False. I have that base_ring is in Fields() and in CommutativeRings(), but can anyone tell me how to make it an instance of CommutativeRings?
