We have the following indirect implication of form equivalence classes:

39 \(\Rightarrow\) 341 given by the following sequence of implications, with a reference to its direct proof:

Implication	Reference
39 \(\Rightarrow\) 8	clear
8 \(\Rightarrow\) 341	clear

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

Howard-Rubin Number	Statement
39:	\(C(\aleph_{1},\infty)\): Every set \(A\) of non-empty sets such that \(\vert A\vert = \aleph_{1}\) has a choice function. Moore, G. [1982], p. 202.
8:	\(C(\aleph_{0},\infty)\):
341:	Every Lindelöf metric space is second countable.
