We have the following indirect implication of form equivalence classes:

30 \(\Rightarrow\) 83
given by the following sequence of implications, with a reference to its direct proof:

Implication Reference
30 \(\Rightarrow\) 83 note-81

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

Howard-Rubin Number Statement
30:

Ordering Principle: Every set can be linearly ordered.

83:

\(E(I,II)\) Howard/Yorke [1989]: \(T\)-finite is equivalent to finite.
