The following diagram shows that 111 \(\not \Rightarrow\) 47-n 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 80 \( \not \Rightarrow \) 47-n is not just a code 6 non-implication, but is also a code 4 non-implication.
| 47-n | This form is negation transferable | |||
| \(\Downarrow\) | ||||
| This form is transferable | 111 | \( \not \Rightarrow \) | 288-n | |
| \( \Downarrow \) | ||||
| 80 |
