The following diagram shows that 40 \(\not \Rightarrow\) 407 is a code 6 non-implication, and the theory of transferability then shows that it is actually a code 4. It follows that the non-implication 379 \( \not \Rightarrow \) 407 is not just a code 6 non-implication, but is also a code 4 non-implication.
