We have the following indirect implication of form equivalence classes:
| Implication | Reference |
|---|---|
| 9 \(\Rightarrow\) 0 |
Here are the links and statements of the form equivalence classes referenced above:
| Howard-Rubin Number | Statement |
|---|---|
| 9: | Finite \(\Leftrightarrow\) Dedekind finite: \(W_{\aleph_{0}}\) Jech [1973b]: \(E(I,IV)\) Howard/Yorke [1989]): Every Dedekind finite set is finite. |
| 0: | \(0 = 0\). |
