Implications

We have the following indirect implication of form equivalence classes:

42 \(\Rightarrow\) 42
given by the following sequence of implications, with a reference to its direct proof:

Implication Reference
42 \(\Rightarrow\) 42 Zermelo's Axiom of Choice, Moore, 1982, 251

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

Howard-Rubin Number Statement
42:

Löwenheim-Skolem Theorem: If a countable family of first order  sentences is satisfiable in a set \(M\) then it is satisfiable in a countable subset of \(M\). (See Moore, G. [1982], p. 251 for references.
