The following diagram shows that 130 \(\not \Rightarrow\) 163 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 130 \( \not \Rightarrow \) 163 is not just a code 6 non-implication, but is also a code 4 non-implication.
| This form is transferable | 130 | \( \not \Rightarrow \) | 163 | This form is negation transferable |
