We have the following indirect implication of form equivalence classes:
| Implication | Reference |
|---|---|
| 80 \(\Rightarrow\) 80 |
On the principle of dependent choices, Mostowski, A. 1948, Fund. Math. |
Here are the links and statements of the form equivalence classes referenced above:
| Howard-Rubin Number | Statement |
|---|---|
| 80: | \(C(\aleph_{0},2)\): Every denumerable set of pairs has a choice function. |
| 80: | \(C(\aleph_{0},2)\): Every denumerable set of pairs has a choice function. |
