The following diagram shows that 363 \(\not \Rightarrow\) 183-alpha 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 363 \( \not \Rightarrow \) 183-alpha is not just a code 6 non-implication, but is also a code 4 non-implication.
| 91 | \( \not \Rightarrow \) | 183-alpha | This form is negation transferable | |
| \( \Downarrow \) | ||||
| This form is transferable | 363 |
