Hypothesis: HR 305:

There are \(2^{\aleph_0}\) Vitali equivalence classes. (Vitali equivalence classes are equivalence classes of the real numbers under the relation \(x\equiv y\leftrightarrow(\exists q\in{\Bbb Q})(x-y=q)\).). \ac{Kanovei} \cite{1991}.

Conclusion: HR 221:

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

List of models where hypothesis is true and the conclusion is false:
