We have the following indirect implication of form equivalence classes:

1 \(\Rightarrow\) 143
given by the following sequence of implications, with a reference to its direct proof:

Implication Reference
1 \(\Rightarrow\) 143

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.

143:

\(H(C,TR)\): If \((X,R)\) is a connected relation (\(u\neq v\rightarrow u\mathrel R v\) or \(v\mathrel R u\)) then \(X\) contains a \(\subseteq\)-maximal transitive subset.
