Implications

We have the following indirect implication of form equivalence classes:

233 \(\Rightarrow\) 242
given by the following sequence of implications, with a reference to its direct proof:

Implication Reference
233 \(\Rightarrow\) 242 clear

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

Howard-Rubin Number Statement
233:

Artin-Schreier theorem: If a field has an algebraic closure it is unique up to isomorphism.

242:

There is, up to an isomorphism, at most one algebraic closure of \({\Bbb Q}\).
