We have the following indirect implication of form equivalence classes:
| Implication | Reference |
|---|---|
| 91 \(\Rightarrow\) 130 | Equivalents of the Axiom of Choice II, Rubin, 1985, theorem 5.7 |
Here are the links and statements of the form equivalence classes referenced above:
| Howard-Rubin Number | Statement |
|---|---|
| 91: | \(PW\): The power set of a well ordered set can be well ordered. |
| 130: | \({\cal P}(\Bbb R)\) is well orderable. |
