We have the following indirect implication of form equivalence classes:

36 \(\Rightarrow\) 343
given by the following sequence of implications, with a reference to its direct proof:

Implication Reference
36 \(\Rightarrow\) 343 On Loeb and weakly Loeb Hausdorff spaces, Tachtsis, E. 2000, Math. Japon.

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

Howard-Rubin Number Statement
36:

Compact T\(_2\) spaces are Loeb. (A space is Loeb if the set of non-empty closed sets has a choice function.)

343:

A product of non-empty, compact \(T_2\) topological spaces is non-empty.
