Proof step 7 from proof abs-gstore-idcircle (previous step)

# lpt = # avol1, # avol0 = # avol1, lpt[n0] = mklp(m3, m4, lpf0, m5), gstore[n0] = groupblock(gndx, lax, m), lpt[n] = mklp(m0, m1, lpf, m2), n < # avol1, id○(avol0, avol1, n), ∀ n. (n < # avol1 ∧ lpt[n].flags = LP_GROUP_NODES ↔ n ∈ gstore) ∧ (n ∈ gstore ∧ ¬ n ∈ ginval → abs-leb(avol0[n], gstore[n], lpt[n])) ∧ (n ∈ gstore → lpt[n].ref-size = gstore[n].ref-size) ⊦ lpf = LP_GROUP_NODES, (n0 < # avol1 ∧ lpf0 = LP_GROUP_NODES ↔ n0 ∈ gstore) ∧ (n0 ∈ gstore ∧ ¬ n0 ∈ ginval → abs-leb(avol1[n0], groupblock(gndx, lax, m), mklp(m3, m4, lpf0, m5))) ∧ (n0 ∈ gstore → m3 = m)

Proof step 8:
# avol0 = # avol1, # lpt = # avol1, n0 < # avol1 ∧ lpt[n0].flags = LP_GROUP_NODES ↔ n0 ∈ gstore, lpt[n] = mklp(m0, m1, lpf, m2), gstore[n0] = groupblock(gndx, lax, m), lpt[n0] = mklp(m3, m4, lpf0, m5), n < # avol1, id○(avol0, avol1, n), n0 ∈ gstore ∧ ¬ n0 ∈ ginval → abs-leb(avol0[n0], gstore[n0], lpt[n0]), n0 ∈ gstore → lpt[n0].ref-size = gstore[n0].ref-size ⊦ lpf = LP_GROUP_NODES, (n0 < # avol1 ∧ lpf0 = LP_GROUP_NODES ↔ n0 ∈ gstore) ∧ (n0 ∈ gstore ∧ ¬ n0 ∈ ginval → abs-leb(avol1[n0], groupblock(gndx, lax, m), mklp(m3, m4, lpf0, m5))) ∧ (n0 ∈ gstore → m3 = m)
