Proof step 18 from proof abs-gstore-set-refsize (previous step)

gstore[n] = groupblock(gndx1, lax1, m4), lpt[n] = mklp(m4, m6, LP_GROUP_NODES, m7), n < # lpt, abs-leb(avol[n], groupblock(gndx1, lax1, m4), mklp(m4, m6, LP_GROUP_NODES, m7)), n ∈ gstore ⊦ n ∈ ginval, avol[n].mapped? ∧ abs-nodes(avol[n].data, gndx1, lax1, m6 = LEB_SIZE) ∧ (m6 ≠ LEB_SIZE → m6 = # avol[n].data)

User applied rule insert rewrite lemma

And obtained the following new goals
