We have the following indirect implication of form equivalence classes:
| Implication | Reference |
|---|---|
| 1 \(\Rightarrow\) 365 |
Here are the links and statements of the form equivalence classes referenced above:
| Howard-Rubin Number | Statement |
|---|---|
| 1: | \(C(\infty,\infty)\): The Axiom of Choice: Every set of non-empty sets has a choice function. |
| 365: | For every uncountable set \(A\), if \(A\) has the same cardinality as each of its uncountable subsets then \(|A| = \aleph_1\). |
