The following diagram shows that 313 \(\not \Rightarrow\) 119 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 313 \( \not \Rightarrow \) 119 is not just a code 6 non-implication, but is also a code 4 non-implication.
| 91 | \( \not \Rightarrow \) | 119 | This form is negation transferable | |
| \( \Downarrow \) | ||||
| This form is transferable | 313 |
