We have the following indirect implication of form equivalence classes:

232 \(\Rightarrow\) 232
given by the following sequence of implications, with a reference to its direct proof:

Implication Reference
232 \(\Rightarrow\) 232

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

Howard-Rubin Number Statement
232:

Every metric space \((X,d)\) has a \(\sigma\)-point finite base.
