The subproof is completed by applying H4.
Assume H5:
and (and (and (x5 = x0) (∀ x10 . prim1 x10 x5 ⟶ ∀ x11 . prim1 x11 x5 ⟶ x6 x10 x11 = x1 x10 x11)) (∀ x10 . prim1 x10 x5 ⟶ x7 x10 = x2 x10)) (∀ x10 . prim1 x10 x5 ⟶ x8 x10 = x3 x10).
Apply H5 with
x9 = x4 ⟶ ∀ x10 . prim1 x10 x0 ⟶ ∀ x11 . prim1 x11 x0 ⟶ prim1 (x1 x10 x11) x0.
Assume H6:
and (and (x5 = x0) (∀ x10 . prim1 x10 x5 ⟶ ∀ x11 . prim1 x11 x5 ⟶ x6 x10 x11 = x1 x10 x11)) (∀ x10 . prim1 x10 x5 ⟶ x7 x10 = x2 x10).
Apply H6 with
(∀ x10 . prim1 x10 x5 ⟶ x8 x10 = x3 x10) ⟶ x9 = x4 ⟶ ∀ x10 . prim1 x10 x0 ⟶ ∀ x11 . prim1 x11 x0 ⟶ prim1 (x1 x10 x11) x0.
Assume H7:
and (x5 = x0) (∀ x10 . prim1 x10 x5 ⟶ ∀ x11 . prim1 x11 x5 ⟶ x6 x10 x11 = x1 x10 x11).
Apply H7 with
(∀ x10 . prim1 x10 x5 ⟶ x7 x10 = x2 x10) ⟶ (∀ x10 . prim1 x10 x5 ⟶ x8 x10 = x3 x10) ⟶ x9 = x4 ⟶ ∀ x10 . prim1 x10 x0 ⟶ ∀ x11 . prim1 x11 x0 ⟶ prim1 (x1 x10 x11) x0.
Assume H8: x5 = x0.
