Let x0 of type ((ιι) → ι) → ((((ιι) → ιι) → ι) → (ιι) → (ιι) → ιι) → ι be given.
Let x1 of type (((CN (ιι)) → ι) → ι) → (ιι(ιι) → ι) → ι((ιι) → ιι) → ι be given.
Let x2 of type (((ιι) → CT2 ι) → ι) → ιι be given.
Let x3 of type (ιι) → ((((ιι) → ιι) → ι) → ι) → (ιι) → ι be given.
Assume H0: ∀ x4 : (((ι → ι)ι → ι)(ι → ι) → ι) → ι . ∀ x5 . ∀ x6 : ι → ι . ∀ x7 . x3 (λ x8 . x8) (λ x8 : ((ι → ι)ι → ι) → ι . 0) (λ x8 . 0) = x5.
