We have the following indirect implication of form equivalence classes:

133 \(\Rightarrow\) 340
given by the following sequence of implications, with a reference to its direct proof:

Implication Reference
133 \(\Rightarrow\) 340 note-157

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

Howard-Rubin Number Statement
133:  

Every set is either well orderable or has an infinite amorphous subset.

340:

Every Lindelöf metric space is separable.
