We have the following indirect implication of form equivalence classes:

367 \(\Rightarrow\) 93
given by the following sequence of implications, with a reference to its direct proof:

Implication Reference
367 \(\Rightarrow\) 366 Eine Basis aller Zahlen und die unstetigen Losungen der Functionalgleichung: \(f(x+y) = f(x) + f(y)\), Hamel, G. 1905, Math. Ann.
366 \(\Rightarrow\) 93 Zermelo's Axiom of Choice, Moore, 1982, table 5

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

Howard-Rubin Number Statement
367:

There is a Hamel basis for \(\Bbb R\) as a vector space over \(\Bbb Q\).

366:

There is a discontinuous function \(f: \Bbb R \to\Bbb R\) such that for all real \(x\) and \(y\), \(f(x+y)=f(x)+f(y)\).

93:

There is a non-measurable subset of \({\Bbb R}\).
