This non-implication,
Form 198 \( \not \Rightarrow \)
Form 296,
whose code is 4, is constructed around a proven non-implication as follows:
Hypothesis | Statement |
---|---|
Form 295 | <p> <strong>DO:</strong> Every infinite set has a dense linear ordering. </p> |
Conclusion | Statement |
---|---|
Form 296 | <p> <strong>Part-\(\infty\):</strong> Every infinite set is the disjoint union of infinitely many infinite sets. </p> |
The conclusion Form 198 \( \not \Rightarrow \) Form 296 then follows.
Finally, the
List of models where hypothesis is true and the conclusion is false:

\(\cal N48\) Pincus' Model XI | \(\cal A=(A,<,C_0,C_1,\dots)\) is called an<em>ordered colored set</em> (OC set) if \(<\) is a linear ordering on \(A\)and the \(C_i\), for \(i\in\omega\) are subsets of \(A\) such that for each\(a\in A\) there is exactly one \(n\in\omega\) such that \(a\in C_n\) |
