We have the following indirect implication of form equivalence classes:

221 \(\Rightarrow\) 222
given by the following sequence of implications, with a reference to its direct proof:

Implication Reference
221 \(\Rightarrow\) 222 clear

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

Howard-Rubin Number Statement
221:

For all infinite \(X\), there is a non-principal measure on \(\cal P(X)\).

222:

There is a non-principal measure on \(\cal P(\omega)\).
