We have the following indirect implication of form equivalence classes:
| Implication | Reference |
|---|---|
| 1 \(\Rightarrow\) 90 |
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. |
| 90: | \(LW\): Every linearly ordered set can be well ordered. Jech [1973b], p 133. |
