Implications

This non-implication, Form 415 \( \not \Rightarrow \) Form 293, whose code is 6, is constructed around a proven non-implication as follows:

  • An (optional) implication of code 1 or code 2 is given. In this case, it's Code 2: 9668, whose string of implications is:
    144 \(\Rightarrow\) 415
  • A proven non-implication whose code is 5. In this case, it's Code 3: 411, Form 144 \( \not \Rightarrow \) Form 293 whose summary information is:
    Hypothesis Statement
    Form 144 <p> Every set is almost well orderable. </p>

    Conclusion Statement
    Form 293 <p> For all sets \(x\) and \(y\), if \(x\) can be linearly ordered and there is a mapping of \(x\) onto \(y\), then \(y\) can be linearly ordered. </p>

  • This non-implication was constructed without the use of this last code 2/1 implication

The conclusion Form 415 \( \not \Rightarrow \) Form 293 then follows.

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

Name Statement
\(\cal N37\) A variation of Blass' model, \(\cal N28\) Let \(A=\{a_{i,j}:i\in\omega, j\in\Bbb Z\}\)
