Claim L0: ∀ x0 x1 x2 . (λ x3 x4 . False) x0 x1(λ x3 x4 . False) x0 x2x1 = x2
Let x0 of type ι be given.
Let x1 of type ι be given.
Let x2 of type ι be given.
Assume H0: False.
Apply FalseE with (λ x3 x4 . False) x0 x2x1 = x2.
The subproof is completed by applying H0.
Claim L1: ∃ x0 . ∀ x1 . iff (prim1 x1 x0) (∃ x2 . and (prim1 x2 (prim0 (λ x3 . False))) False)
Apply unknownprop_aaea0f1d3f5e853f0d3287d822ec5f356e024921388ea00672dad551690ba08f with prim0 (λ x0 . False), λ x0 x1 . False.
The subproof is completed by applying L0.
Apply L1 with ∃ x0 . ∀ x1 . nIn x1 x0.
Let x0 of type ι be given.
Assume H2: ∀ x1 . iff (prim1 x1 x0) (∃ x2 . and (prim1 x2 (prim0 (λ x3 . False))) False).
Let x1 of type ο be given.
Assume H3: ∀ x2 . (∀ x3 . nIn x3 x2)x1.
Apply H3 with x0.
Let x2 of type ι be given.
Assume H4: prim1 x2 x0.
Apply H2 with x2, False.
Assume H5: prim1 x2 x0∃ x3 . and (prim1 x3 (prim0 (λ x4 . False))) False.
Assume H6: (∃ x3 . and (prim1 x3 (prim0 (λ x4 . False))) False)prim1 x2 x0.
Apply H5 with False leaving 2 subgoals.
The subproof is completed by applying H4.
Let x3 of type ι be given.
Assume H7: (λ x4 . and (prim1 x4 (prim0 (λ x5 . False))) False) x3.
Apply H7 with False.
Assume H8: prim1 x3 (prim0 (λ x4 . False)).
Assume H9: False.
The subproof is completed by applying H9.
