Implications

We have the following indirect implication of form equivalence classes:

102 \(\Rightarrow\) 102
given by the following sequence of implications, with a reference to its direct proof:

Implication Reference
102 \(\Rightarrow\) 102 The Axiom of Choice, Jech, 1973b, page 162 problem 11.12

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

Howard-Rubin Number Statement
102:

For all Dedekind finite cardinals \(p\) and \(q\), if \(p^{2} = q^{2}\) then \(p = q\). Jech [1973b], p 162 prob 11.12.

102:

For all Dedekind finite cardinals \(p\) and \(q\), if \(p^{2} = q^{2}\) then \(p = q\). Jech [1973b], p 162 prob 11.12.
