Proof step 1 from proof refsize-nonzero-notin-ginval (conclusion)

⊦ gstore[n] = groupblock(gndx, lax, m2) ∧ n ∈ gstore ∧ m2 ≠ 0 ∧ refsize-cons(gstore, range ri) ∧ ri-cons(ri, nodes(gstore ↓, ginval)) ∧ inv(gstore \ ginval) → ¬ n ∈ ginval

System applied rule normalize

And obtained the following new goals

Proof step 2:
gstore[n] = groupblock(gndx, lax, m2), inv(gstore \ ginval), refsize-cons(gstore, range ri), ri-cons(ri, nodes(gstore ↓, ginval)), n ∈ ginval, n ∈ gstore ⊦ m2 = 0

Proof step 1 from proof refsize-nonzero-notin-ginval (conclusion)

System applied rule normalize

And obtained the following new goals
