We have the following indirect implication of form equivalence classes:

144 \(\Rightarrow\) 414
given by the following sequence of implications, with a reference to its direct proof:

Implication Reference
144 \(\Rightarrow\) 414 Constructive order theory, Ern'e, M. 2001, Math. Logic Quart.

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

Howard-Rubin Number Statement
144:

Every set is almost well orderable.

414:

Every \(\cal W\)-frame is a \(\cal D\)-frame.  \ac{Ern\'e} \cite{2000}
