We have the following indirect implication of form equivalence classes:

280 \(\Rightarrow\) 280
given by the following sequence of implications, with a reference to its direct proof:

280 \(\Rightarrow\) 280

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

Howard-Rubin Number Statement
280:

There is a complete separable metric space with a subset which does not have the Baire property.
