Proof step 4 from proof abs-gstore-set-lebsize (previous step)

lpt[n] = mklp(n0, n1, LP_GROUP_NODES, n2), gstore[n3] = groupblock(gndx, lax, m), n < # avol, ∀ n. (n < # lpt ∧ lpt[n].flags = LP_GROUP_NODES ↔ n ∈ gstore) ∧ (n ∈ gstore ∧ ¬ n ∈ ginval → abs-leb(avol[n], gstore[n], lpt[n])) ∧ (n ∈ gstore → lpt[n].ref-size = gstore[n].ref-size) ⊦ (n3 < # lpt ∧ lpt[n, mklp(n0, LEB_SIZE, LP_GROUP_NODES, n2)][n3].flags = LP_GROUP_NODES ↔ n3 ∈ gstore) ∧ (n3 ∈ gstore ∧ ¬ n3 ∈ ginval → abs-leb(avol[n3], gstore[n3], lpt[n, mklp(n0, LEB_SIZE, LP_GROUP_NODES, n2)][n3])) ∧ (n3 ∈ gstore → lpt[n, mklp(n0, LEB_SIZE, LP_GROUP_NODES, n2)][n3].ref-size = m)
