Let x0 of type ι be given.
Let x1 of type ιι be given.
Let x2 of type ιο be given.
Assume H0: ∀ x3 . x3x0x2 (x1 x3).
Let x3 of type ι be given.
Assume H1: x3{x1 x4|x4 ∈ x0}.
Apply ReplE_impred with x0, x1, x3, x2 x3 leaving 2 subgoals.
The subproof is completed by applying H1.
Let x4 of type ι be given.
Assume H2: x4x0.
Assume H3: x3 = x1 x4.
Apply H3 with λ x5 x6 . x2 x6.
Apply H0 with x4.
The subproof is completed by applying H2.
