We have the following indirect implication of form equivalence classes:

130 \(\Rightarrow\) 94 given by the following sequence of implications, with a reference to its direct proof:

Implication	Reference
130 \(\Rightarrow\) 79	clear
79 \(\Rightarrow\) 94	clear

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

Howard-Rubin Number	Statement
130:	\({\cal P}(\Bbb R)\) is well orderable.
79:	\({\Bbb R}\) can be well ordered.  Hilbert [1900], p 263.
94:	\(C(\aleph_{0},\infty,{\Bbb R})\): Every denumerable family of non-empty sets of reals  has a choice function. Jech [1973b], p 148 prob 10.1.
