Implications

This non-implication, Form 90 \( \not \Rightarrow \) Form 221, whose code is 6, 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 5. In this case, it's Code 3: 190, Form 90 \( \not \Rightarrow \) Form 221 whose summary information is:
    Hypothesis Statement
    Form 90 <p> \(LW\):  Every linearly ordered set can be well ordered. <a href="/books/8">Jech [1973b]</a>, p 133. </p>

    Conclusion Statement
    Form 221 <p> For all infinite \(X\), there is a non-principal measure on \(\cal P(X)\). </p>

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

The conclusion Form 90 \( \not \Rightarrow \) Form 221 then follows.

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

Name Statement
\(\cal N51\) Weglorz/Brunner Model Let \(A\) be denumerable and \(\cal G\)be the group of all permutations of \(A\)
