Let x0 of type ι be given.
Let x1 of type ι be given.
Apply H0 with
λ x2 . x2 = 11e73.. x0 x1 ⟶ prim1 x1 x0 leaving 2 subgoals.
Let x2 of type ι be given.
Let x3 of type ι be given.
Apply unknownprop_e480fde9d55ddf57a76abb73830d7ca4419d887634ebde1e7b43232933cc979e with
x2,
x0,
x3,
x1,
prim1 x1 x0 leaving 2 subgoals.
The subproof is completed by applying H2.
Assume H3: x2 = x0.
Assume H4: x3 = x1.
Apply H3 with
λ x4 x5 . prim1 x1 x4.
Apply H4 with
λ x4 x5 . prim1 x4 x2.
The subproof is completed by applying H1.
Let x2 of type ι → ι → ο be given.
The subproof is completed by applying H1.
