Let x0 of type ι be given.
Let x1 of type ι → ι be given.
Apply set_ext with
94f9e.. x0 (λ x2 . x1 x2),
a842e.. x0 (λ x2 . 91630.. (x1 x2)) leaving 2 subgoals.
Let x2 of type ι be given.
Apply unknownprop_d908b89102f7b662c739e5a844f67efc8ae1cd05a2e9ce1e3546fa3885f40100 with
x0,
x1,
x2,
prim1 x2 (a842e.. x0 (λ x3 . 91630.. (x1 x3))) leaving 2 subgoals.
The subproof is completed by applying H0.
Let x3 of type ι be given.
Assume H2: x2 = x1 x3.
