We have the following indirect implication of form equivalence classes:
| Implication | Reference |
|---|---|
| 76 \(\Rightarrow\) 173 |
Paracompactness of metric spaces and the axiom of choice, Howard, P. 2000a, Math. Logic Quart. |
Here are the links and statements of the form equivalence classes referenced above:
| Howard-Rubin Number | Statement |
|---|---|
| 76: | \(MC_\omega(\infty,\infty)\) (\(\omega\)-MC): For every family \(X\) of pairwise disjoint non-empty sets, there is a function \(f\) such that for each \(x\in X\), f(x) is a non-empty countable subset of \(x\). |
| 173: | \(MPL\): Metric spaces are para-Lindelöf. |
