Let x0 of type ι be given.
Let x1 of type ι → ι be given.
Let x2 of type ι → ι be given.
Assume H0:
∀ x3 . In x3 x0 ⟶ x1 x3 = x2 x3.
Apply unknownprop_a23ec6a55ac212526d74cbf0d04096929ad453b0eb0f8023e32b8a33930d39fb with
lam x0 (λ x3 . x1 x3),
lam x0 (λ x3 . x2 x3) leaving 2 subgoals.
Apply unknownprop_810fd42bef360cfab16d109f258159f9c4822cd35c399417db217ec64c39c49b with
x0,
x1,
x2.
The subproof is completed by applying H0.

Let x3 of type ι be given.
Let x4 of type ι → ι → ο be given.
Apply H0 with
x3,
λ x5 x6 . x4 x6 x5.
The subproof is completed by applying H1.
