| Implication | Reference |
|---|---|
| 130 \(\Rightarrow\) 79 | clear |
Here are the links and statements of the form equivalence classes referenced above:
| Howard-Rubin Number | Statement |
|---|---|
| 130: | \({\cal P}(\Bbb R)\) is well orderable. |
| 79: | \({\Bbb R}\) can be well ordered. Hilbert [1900], p 263. |
