The following diagram shows that 10 \(\not \Rightarrow\) 17 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 374-n \( \not \Rightarrow \) 17 is not just a code 6 non-implication, but is also a code 4 non-implication.
