This non-implication, Form 79 \( \not \Rightarrow \) Form 278, whose code is 6, is constructed around a proven non-implication as follows:
Note: This non-implication is actually a code 4, as this non-implication satisfies the transferability criterion. Click Transfer details for all the details)

  • An (optional) implication of code 1 or code 2 is given. In this case, it's Code 2: 10129, whose string of implications is:
    91 \(\Rightarrow\) 79
  • A proven non-implication whose code is 5. In this case, it's Code 3: 225, Form 91 \( \not \Rightarrow \) Form 244 whose summary information is:
    Hypothesis Statement
    Form 91 <p> \(PW\):  The power set of a well ordered set can be well ordered. </p>

    Conclusion Statement
    Form 244 <p> Every principal ideal domain has a maximal ideal. </p>

  • An (optional) implication of code 1 or code 2 is given. In this case, it's Code 2: 10232, whose string of implications is:
    278 \(\Rightarrow\) 244

The conclusion Form 79 \( \not \Rightarrow \) Form 278 then follows.
