We have the following indirect implication of form equivalence classes:

79 \(\Rightarrow\) 92
given by the following sequence of implications, with a reference to its direct proof:

Implication Reference
79 \(\Rightarrow\) 92 clear

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

Howard-Rubin Number Statement
79:

\({\Bbb R}\) can be well ordered.  Hilbert [1900], p 263.

92:

\(C(WO,{\Bbb R})\):  Every well ordered family of non-empty subsets of \({\Bbb R}\) has a choice function.
