We have the following indirect implication of form equivalence classes:

62 \(\Rightarrow\) 64
given by the following sequence of implications, with a reference to its direct proof:

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

Howard-Rubin Number Statement
62:

\(C(\infty,< \aleph_{0})\):  Every set of non-empty finite  sets  has  a choice function.

64:

\(E(I,Ia)\) There are no amorphous sets. (Equivalently, every infinite set is the union of two disjoint infinite sets.)
