λ x0 x1 . x1 = ChurchNum_ii_6 ChurchNum2 ordsucc 0 leaving 2 subgoals.
The subproof is completed by applying nat_5.
Apply unknownprop_dfd75789bdcf74d855c762b087b060f27bac1d86daec67bb0564ef3cbdbd7473 with
λ x0 x1 . add_nat (exp_nat 2 5) x1 = ChurchNum_ii_5 ChurchNum2 ordsucc (ChurchNum_ii_5 ChurchNum2 ordsucc 0).
Claim L0: ∀ x2 : ι → ο . x2 y1 ⟶ x2 y0
Let x2 of type ι → ο be given.
