Proof step 66 from proof abs-istore-lpt-change-other (previous step)

lpt[n3] = mklp(m3, m4, lpf1, m5), istore[n3] = indexblock(indx, lax, m2), lpt[n] = mklp(n0, n1, lpf, n2), ∀ n. (n < # lpt ∧ lpt[n].flags = LP_INDEX_NODES ↔ n ∈ istore) ∧ (n ∈ istore → abs-leb(avol[n], istore[n], lpt[n]) ∧ lpt[n].ref-size = istore[n].ref-size) ⊦ lpf = LP_INDEX_NODES, lpf0 = LP_INDEX_NODES, n3 = n, n3 < # lpt, (n3 < # lpt ∧ lpf1 = LP_INDEX_NODES ↔ n3 ∈ istore) ∧ (n3 ∈ istore → abs-leb(avol[n3], indexblock(indx, lax, m2), mklp(m2, m4, lpf1, m5)) ∧ m3 = m2)

Proof step 67:
lpt[n] = mklp(n0, n1, lpf, n2), istore[n3] = indexblock(indx, lax, m2), lpt[n3] = mklp(m3, m4, lpf1, m5), n3 ∈ istore, # lpt ≤ n3, ∀ n. (n < # lpt ∧ lpt[n].flags = LP_INDEX_NODES ↔ n ∈ istore) ∧ (n ∈ istore → abs-leb(avol[n], istore[n], lpt[n]) ∧ lpt[n].ref-size = istore[n].ref-size) ⊦ lpf = LP_INDEX_NODES, lpf0 = LP_INDEX_NODES, n3 = n
