TopTorp92,
I reread your TMA article this morning.
While trying to visualize the various cases in my head, it dawned on me that there are, in fact, only 8 cases. As such the computer systems professional in me cried out, "Why visualize anything? Just produce a TMA for dummies table!"
Please see below. If you would be so kind as to indicate what goes into the 8 missing entries, I would appreciate it!
