| Sep 18, 2013 at 16:50 | comment | added | David E Speyer | May I ask where this question comes from? It is a very fun question, and I can solve it for finite rings. On the other hand, with the finite hypothesis, it would make an excellent challenging homework question for a class on non-commutative ring theory, and I'd rather not give away the answer if it is. | |
