Proof step 11 from proof nodes-referenced-adrs-leb (previous step)

gstore[n] = groupblock(gndx, lax, m), ri-cons(ri, nodes(gstore ↓, ginval)), n ∈ gstore ⊦ adr ∈ lax.to-adr(n) ∧ adr ∈ ri ↔ adr.lnum = n ∧ adr ∈ range ri, n ∈ ginval

And obtained the following new goals

Proof step 12:
gstore[n] = groupblock(gndx, lax, m), ri-cons(ri, nodes(gstore ↓, ginval)), n ∈ gstore, adr ∈ ri ⊦ adr ∈ lax.to-adr(n) ↔ adr.lnum = n, n ∈ ginval

Rule argument
