This non-implication,
Form 163 \( \not \Rightarrow \)
Form 17,
whose code is 4, is constructed around a proven non-implication as follows:
| Hypothesis | Statement |
|---|---|
| Form 163 | <p> Every non-well-orderable set has an infinite, Dedekind finite subset. </p> |
| Conclusion | Statement |
|---|---|
| Form 124 | <p> Every operator on a Hilbert space with an amorphous base is the direct sum of a finite matrix and a scalar operator. (A set is <em>amorphous</em> if it is not the union of two disjoint infinite sets.) </p> |
The conclusion Form 163 \( \not \Rightarrow \) Form 17 then follows.
Finally, the
List of models where hypothesis is true and the conclusion is false:
