Let x0 of type ι → ο be given.
Let x1 of type ι → ο be given.
Let x2 of type ι be given.
Assume H0: x0 x2.
Assume H1: x1 x2.
Let x3 of type ο be given.
Assume H2:
∀ x4 . and (x0 x4) (x1 x4) ⟶ x3.
Apply H2 with
x2.
Apply unknownprop_389e2fb1855352fcc964ea44fe6723d7a1c2d512f04685300e3e97621725b977 with
x0 x2,
x1 x2 leaving 2 subgoals.
The subproof is completed by applying H0.
The subproof is completed by applying H1.
