Apply unknownprop_119979cc2e84a4dcf5abf8bfc1e52b0d535aa820418159d54fb84a561f4b01cc with
λ x5 x6 : (ι → (ι → ο) → ο) → ι → (ι → ο) → ο . x6 x2 x3 x4.
Let x5 of type ο be given.
Assume H3:
∀ x6 . and (ordinal x6) (∃ x7 : ι → ο . and (x2 x6 x7) (PNoLe x3 x4 x6 x7)) ⟶ x5.
Apply H3 with
x0.
Apply unknownprop_389e2fb1855352fcc964ea44fe6723d7a1c2d512f04685300e3e97621725b977 with
ordinal x0,
∃ x6 : ι → ο . and (x2 x0 x6) (PNoLe x3 x4 x0 x6) leaving 2 subgoals.
The subproof is completed by applying H0.
Let x6 of type ο be given.
Assume H4:
∀ x7 : ι → ο . and (x2 x0 x7) (PNoLe x3 x4 x0 x7) ⟶ x6.
