gstore0[n] = groupblock(gndx0, lax0, m0), gstore1[n] = groupblock(gndx, lax, m), n ∈ gstore1, n ∈ gstore0, ∀ n. (n ∈ gstore1 ↔ n ∈ gstore0) ∧ gstore1[n].gndlist = gstore0[n].gndlist ∧ gstore1[n].ladrlist = gstore0[n].ladrlist ⊦ prefixn(valid-group-nodes(gndx), gndx) = prefixn(valid-group-nodes(gndx0), gndx0) ∧ prefixn(valid-group-nodes(gndx), lax) = prefixn(valid-group-nodes(gndx0), lax0)
