Let x0 of type ι → ι → ι be given.
Let x1 of type ι → ι → ι be given.
Apply H0 with
fb516.. (cc64c.. x0 x1) leaving 2 subgoals.
Apply H2 with
λ x2 x3 : ι → ι → ι . fb516.. (cc64c.. x3 x1).
The subproof is completed by applying unknownprop_4b2c4a0487c2b1a228c5d07bbf352ffca25633bec988b0f94ee850e02347e107.
Apply H2 with
λ x2 x3 : ι → ι → ι . fb516.. (cc64c.. x3 x1).
Apply unknownprop_fe36caae5784dcaccf90e3c33c4c3db05a48fc46bf7e1321a13b032e9121e798 with
λ x2 x3 : ι → ι → ι . fb516.. (cc64c.. x3 x1).
The subproof is completed by applying H1.
