Implications

We have the following indirect implication of form equivalence classes:

132 \(\Rightarrow\) 73
given by the following sequence of implications, with a reference to its direct proof:

Implication Reference
132 \(\Rightarrow\) 73 clear

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

Howard-Rubin Number Statement
132:

\(PC(\infty, <\aleph_0,\infty)\):  Every infinite family of finite  sets has an infinite subfamily with a choice function.

73:

\(\forall n\in\omega\), \(PC(\infty,n,\infty)\):  For every \(n\in\omega\), if \(C\) is an infinite family of \(n\) element sets, then \(C\) has an infinite subfamily with a choice function. De la Cruz/Di Prisco [1998b]
