Let x0 of type ι → ι → ι be given.
Let x1 of type ι → ι → ι be given.
Apply H0 with
fb516.. (efcd0.. x0 x1) leaving 2 subgoals.
Apply H2 with
λ x2 x3 : ι → ι → ι . fb516.. (efcd0.. x3 x1).
The subproof is completed by applying unknownprop_5066d1b2b30c335c067f01ac13f147e53d00378a90e5b6ab1432446a8181f6dd.
Apply H2 with
λ x2 x3 : ι → ι → ι . fb516.. (efcd0.. x3 x1).
Apply unknownprop_fe36caae5784dcaccf90e3c33c4c3db05a48fc46bf7e1321a13b032e9121e798 with
λ x2 x3 : ι → ι → ι . fb516.. (λ x4 x5 . x3 x5 (x1 x4 x5)).
The subproof is completed by applying H1.
