Let x0 of type ι be given.
Let x1 of type ι → ι be given.
Let x2 of type ι be given.
Apply H0 with
λ x3 . x3 = 8eacd.. x0 x1 x2 ⟶ prim1 x2 x0 leaving 2 subgoals.
Let x3 of type ι be given.
Let x4 of type ι → ι be given.
Let x5 of type ι be given.
Apply unknownprop_98aa881f9d512466d5d34d1715cd6bef507b937a21868becb15373f2e71762e4 with

The subproof is completed by applying H3.
Assume H4:
and (x3 = x0) (∀ x6 . prim1 x6 x3 ⟶ x4 x6 = x1 x6).
Apply H4 with
x5 = x2 ⟶ prim1 x2 x0.
Assume H5: x3 = x0.
Assume H6:
∀ x6 . prim1 x6 x3 ⟶ x4 x6 = x1 x6.
Assume H7: x5 = x2.
Apply H5 with
λ x6 x7 . prim1 x2 x6.
Apply H7 with
λ x6 x7 . prim1 x6 x3.
The subproof is completed by applying H2.
Let x3 of type ι → ι → ο be given.
The subproof is completed by applying H1.
