We have the following indirect implication of form equivalence classes:
| Implication | Reference |
|---|---|
| 1 \(\Rightarrow\) 16 |
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. |
| 16: | \(C(\aleph_{0},\le 2^{\aleph_{0}})\): Every denumerable collection of non-empty sets each with power \(\le 2^{\aleph_{0}}\) has a choice function. |
