We have the following indirect implication of form equivalence classes:
| Implication | Reference |
|---|---|
| 386 \(\Rightarrow\) 10 |
Products, the Baire category theorem, and the axiom of dependent choice, Herrlich-Keremedis-1999a[1999a], Topology and its Applications. |
| 10 \(\Rightarrow\) 216 |
Here are the links and statements of the form equivalence classes referenced above:
| Howard-Rubin Number | Statement |
|---|---|
| 386: | Every B compact (pseudo)metric space is Baire. |
| 10: | \(C(\aleph_{0},< \aleph_{0})\): Every denumerable family of non-empty finite sets has a choice function. |
| 216: | Every infinite tree has either an infinite chain or an infinite antichain. |
