Let x0 of type ι → (ι → ο) → ο be given.
Let x1 of type ι → (ι → ο) → ο be given.
Assume H0: ed32f.. x0 x1.
Let x2 of type ι be given.
Assume H1: ordinal x2.
Assume H2: PNo_lenbdd x2 x0.
Assume H3: PNo_lenbdd x2 x1.
Apply unknownprop_d8fa879768f1bd3a3b56ab28639ef7542e561b58283cb61604eb09431a55cb04 with x0, x1, x2, 1a487.. x0 x1 (7b9f3.. x0 x1) (ce2d5.. x0 x1) leaving 5 subgoals.
The subproof is completed by applying H0.
The subproof is completed by applying H1.
The subproof is completed by applying H2.
The subproof is completed by applying H3.
Assume H4: 1a487.. x0 x1 (7b9f3.. x0 x1) (ce2d5.. x0 x1).
Assume H5: ∀ x3 . nIn x3 (7b9f3.. x0 x1) ⟶ not (ce2d5.. x0 x1 x3).
The subproof is completed by applying H4.
