The following diagram shows that 130 \(\not \Rightarrow\) 216 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 130 \( \not \Rightarrow \) 216 is not just a code 6 non-implication, but is also a code 4 non-implication.
