We have the following indirect implication of form equivalence classes:
| Implication | Reference |
|---|---|
| 1 \(\Rightarrow\) 98 |
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. |
| 98: | The set of all finite subsets of a Dedekind finite set is Dedekind finite. Jech [1973b] p 161 prob 11.5. |
