Let x0 of type ι(ιιο) → (ιο) → ο be given.
Let x1 of type ι be given.
Let x2 of type ιιο be given.
Let x3 of type ιο be given.
Assume H0: ∀ x4 : ι → ι → ο . (∀ x5 . prim1 x5 x1∀ x6 . prim1 x6 x1iff (x2 x5 x6) (x4 x5 x6))∀ x5 : ι → ο . (∀ x6 . prim1 x6 x1iff (x3 x6) (x5 x6))x0 x1 x4 x5 = x0 x1 x2 x3.
Apply unknownprop_59ca09c0fd122f786673713c0642ed4ce1a31aabde53a2b0a8368edd8a739e79 with x1, x2, x3, λ x4 x5 . x0 x4 (2b2e3.. (f482f.. (42836.. x1 x2 x3) (4ae4a.. 4a7ef..))) (decode_p (f482f.. (42836.. x1 x2 x3) (4ae4a.. (4ae4a.. 4a7ef..)))) = x0 x1 x2 x3.
Apply H0 with 2b2e3.. (f482f.. (42836.. x1 x2 x3) (4ae4a.. 4a7ef..)), decode_p (f482f.. (42836.. x1 x2 x3) (4ae4a.. (4ae4a.. 4a7ef..))) leaving 2 subgoals.
