The following diagram shows that 130 \(\not \Rightarrow\) 164 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 104 \( \not \Rightarrow \) 164 is not just a code 6 non-implication, but is also a code 4 non-implication.

This form is transferable 130 \( \not \Rightarrow \) 164 This form is negation transferable
