We have the following indirect implication of form equivalence classes:
| Implication | Reference |
|---|---|
| 427 \(\Rightarrow\) 67 | clear |
| 67 \(\Rightarrow\) 116 | clear |
Here are the links and statements of the form equivalence classes referenced above:
| Howard-Rubin Number | Statement |
|---|---|
| 427: | \(\exists F\) AL20(\(F\)): There is a field \(F\) such that every vector space \(V\) over \(F\) has the property that every independent subset of \(V\) can be extended to a basis. \ac{Bleicher} \cite{1964}, \ac{Rubin, H.\/Rubin, J \cite{1985, p.119, AL20}. |
| 67: | \(MC(\infty,\infty)\) \((MC)\), The Axiom of Multiple Choice: For every set \(M\) of non-empty sets there is a function \(f\) such that \((\forall x\in M)(\emptyset\neq f(x)\subseteq x\) and \(f(x)\) is finite). |
| 116: | Every compact \(T_2\) space is weakly Loeb. Weakly Loeb means the set of non-empty closed subsets has a multiple choice function. |
