We have the following indirect implication of form equivalence classes:
			
| Implication | Reference | 
|---|---|
| 1 \(\Rightarrow\) 158 | 
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. | 
| 158: | In every Hilbert space \(H\), if the closed unit ball is sequentially compact, then \(H\) has an orthonormal basis. |
