We have the following indirect implication of form equivalence classes:
| Implication | Reference |
|---|---|
| 41 \(\Rightarrow\) 365 | Zermelo's Axiom of Choice, Moore, 1982, table 5 |
Here are the links and statements of the form equivalence classes referenced above:
| Howard-Rubin Number | Statement |
|---|---|
| 41: | \(W_{\aleph _{1}}\): For every cardinal \(m\), \(m \le \aleph_{1}\) or \(\aleph_{1}\le m \). |
| 365: | For every uncountable set \(A\), if \(A\) has the same cardinality as each of its uncountable subsets then \(|A| = \aleph_1\). |
