\(\displaystyle{ Ax_1 \vdash f(2449)=(\neg (x \in y \wedge y \in x))\Rightarrow(z=z \Rightarrow(\neg (x \in y \wedge y \in x)) )}\)
\(\displaystyle{ f(2447),f(2449),MP \vdash f(2450)=z=z \Rightarrow(\neg (x \in y \wedge y \in x))}\)
\(\displaystyle{ R1,f(2450) \vdash f(2451)=z=z \Rightarrow (\forall y(\neg (x \in y \wedge y \in x)))}\)
\(\displaystyle{ R1, f(2451) \vdash f(2452)=z=z \Rightarrow (\forall x(\forall y(\neg (x \in y \wedge y \in x))))}\)
\(\displaystyle{ f(2448),f(2452),MP \vdash f(2453)=\forall x(\forall y(\neg (x \in y \wedge y \in x)))}\)
- to oczywiście nieprawda (tzn. jest to twierdzenie, ale nie podpada pod \(\displaystyle{ AK1}\)). Powinno być na przykład:\(\displaystyle{ AK1 \vdash f(296)=(x \in a \wedge x \in w)\Rightarrow(\exists z (z \in a \wedge z \in w) )}\)
\(\displaystyle{ AK1 \vdash f(296)=(z \in a \wedge z \in w)\Rightarrow(\exists z (z \in a \wedge z \in w) )}\)
\(\displaystyle{ RP,f(296)\vdash f(297)=(x \in a \wedge x \in w)\Rightarrow(\exists z (z \in a \wedge z \in w) )}\)
W takim wypadku należy w pierwotnej wersji zastąpić
przez \(\displaystyle{ AK1 \vdash f(296)=(z \in a \wedge z \in w)\Rightarrow(\exists z (z \in a \wedge z \in w) )}\) i bezpośrednio pod tym zastąpieniem umieścić \(\displaystyle{ RP,f(296)\vdash f(297)=(x \in a \wedge x \in w)\Rightarrow(\exists z (z \in a \wedge z \in w) )}\), a poniższe \(\displaystyle{ f(x)}\) zastąpić przez \(\displaystyle{ f(x+1)}\) dla \(\displaystyle{ x \ge 296}\) (dostosowanie numeracji do wprowadzonej zmiany)\(\displaystyle{ AK1 \vdash f(296)=(x \in a \wedge x \in w)\Rightarrow(\exists z (z \in a \wedge z \in w) )}\)
