Let x0 of type ι be given.
Let x1 of type ι → ο be given.
Apply unknownprop_ee0b4b64aba8e6af97035d72b359ab8e1ae1e5e06024c58477c9410cad648356 with
λ x2 x3 : ι → (ι → ο) → (ι → ο) → ο . x3 x0 x1 x1.
Let x2 of type ι be given.
The subproof is completed by applying unknownprop_00f3675b03ca269a8c79b213adec0a88ac62c517087fb97bcaaa311794c5691c with x1 x2.
