Axiom Of Choice

We have the following indirect implication of form equivalence classes:

256 \(\Rightarrow\) 256 given by the following sequence of implications, with a reference to its direct proof:

Implication	Reference
256 \(\Rightarrow\) 256

Here are the links and statements of the form equivalence classes referenced above:

Howard-Rubin Number	Statement
256:	\(Z(P,F)\): Every partially ordered set \((X,R)\) in which every forest \(A\) has an upper bound, has a maximal element.
256:	\(Z(P,F)\): Every partially ordered set \((X,R)\) in which every forest \(A\) has an upper bound, has a maximal element.
