Implications

This non-implication, Form 0 \( \not \Rightarrow \) Form 189, whose code is 4, is constructed around a proven non-implication as follows:

  • This non-implication was constructed without the use of this first code 2/1 implication.
  • A proven non-implication whose code is 3. In this case, it's Code 3: 15, Form 0 \( \not \Rightarrow \) Form 190 whose summary information is:
    Hypothesis Statement
    Form 0  \(0 = 0\).

    Conclusion Statement
    Form 190 <p> There is a non-trivial injective Abelian group. </p>

  • An (optional) implication of code 1 or code 2 is given. In this case, it's Code 2: 9616, whose string of implications is:
    189 \(\Rightarrow\) 190

The conclusion Form 0 \( \not \Rightarrow \) Form 189 then follows.

Finally, the
List of models where hypothesis is true and the conclusion is false:

Name Statement
\(\cal M24\) Blass' Model Let \(\cal M\) be a countable transitive model of \(ZFC + V = L\)
\(\cal N28\) Blass' Permutation Model The set \(A=\{a^i_{\xi}: i\in \Bbb Z, \xi\in\aleph_1\}\)
