We have the following indirect implication of form equivalence classes:

133 \(\Rightarrow\) 91
given by the following sequence of implications, with a reference to its direct proof:

133 \(\Rightarrow\) 91 Amorphe Potenzen kompakter Raume, Brunner, N. 1984b, Arch. Math. Logik Grundlagenforschung

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.

91:

\(PW\):  The power set of a well ordered set can be well ordered.
