The following diagram shows that 88 \(\not \Rightarrow\) 250 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 269 \( \not \Rightarrow \) 250 is not just a code 6 non-implication, but is also a code 4 non-implication.
