Proof step 25 from proof in-rm-v (previous step)

eq-entry(m, lref) ∈ (v0 = v ⊃ q0 - v;eq-entry(m0, v0 × m1) ' + (q0 - v)), ∀ m, lref, v. eq-entry(m, lref) ∈ q0 - v → (∃ eqent0. eqent0.pnum = m ∧ eqent0 ∈ q0) ⊦ ∃ eqent0. eqent0.pnum = m ∧ (eqent0 = eq-entry(m0, v0 × m1) ∨ eqent0 ∈ q0)

And obtained the following new goals

Proof step 26:
v0 = v, eq-entry(m, lref) ∈ (v0 = v ⊃ q0 - v;eq-entry(m0, v0 × m1) ' + (q0 - v)), ∀ m, lref, v. eq-entry(m, lref) ∈ q0 - v → (∃ eqent0. eqent0.pnum = m ∧ eqent0 ∈ q0) ⊦ ∃ eqent0. eqent0.pnum = m ∧ (eqent0 = eq-entry(m0, v0 × m1) ∨ eqent0 ∈ q0)
Proof step 34:
eq-entry(m, lref) ∈ (v0 = v ⊃ q0 - v;eq-entry(m0, v0 × m1) ' + (q0 - v)), ∀ m, lref, v. eq-entry(m, lref) ∈ q0 - v → (∃ eqent0. eqent0.pnum = m ∧ eqent0 ∈ q0) ⊦ v0 = v, ∃ eqent0. eqent0.pnum = m ∧ (eqent0 = eq-entry(m0, v0 × m1) ∨ eqent0 ∈ q0)
