We have the following indirect implication of form equivalence classes:

374-n \(\Rightarrow\) 0
given by the following sequence of implications, with a reference to its direct proof:

Implication Reference
374-n \(\Rightarrow\) 0

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

Howard-Rubin Number Statement
374-n:

\(UT(\aleph_0,n,\aleph_0)\) for \(n\in\omega -\{0,1\}\): The union of a denumerable set of \(n\)-element sets is denumerable.

0:  \(0 = 0\).
