We have the following indirect implication of form equivalence classes:

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

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

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

Howard-Rubin Number Statement
271-n:

If \(n\in\omega-\{0,1\}\), \(CT_{n}\): The compactness theorem for propositional logic restricted to sets of formulas in which each variable occurs in at most \(n\) formulas.

0:  \(0 = 0\).
