This non-implication,
Form 189 \( \not \Rightarrow \)
Form 308-p,
whose code is 6,
is constructed around a proven non-implication as follows:
Hypothesis | Statement |
---|---|
Form 191 | <p> \(SVC\): There is a set \(S\) such that for every set \(a\), there is an ordinal \(\alpha\) and a function from \(S\times\alpha\) onto \(a\). </p> |
Conclusion | Statement |
---|---|
Form 308-p | <p> If \(p\) is a prime and if \(\{G_y: y\in Y\}\) is a set of finite groups, then the weak direct product \(\prod_{y\in Y}G_y\) has a maximal \(p\)-subgroup. </p> |
The conclusion Form 189 \( \not \Rightarrow \) Form 308-p then follows.
Finally, the
List of models where hypothesis is true and the conclusion is false:

\(\cal N6\) Levy's Model I | \(A=\{a_n : n\in\omega\}\) and \(A = \bigcup \{P_n: n\in\omega\}\), where \(P_0 = \{a_0\}\), \(P_1 = \{a_1,a_2\}\), \(P_2 =\{a_3,a_4,a_5\}\), \(P_3 = \{a_6,a_7,a_8,a_9,a_{10}\}\), \(\cdots\); in generalfor \(n>0\), \(|P_n| = p_n\), where \(p_n\) is the \(n\)th prime |
