Proof step 70 from proof addarray-put-01 (previous step)

0 < i0, 0 < i, r -- i ' ∈ addarray(r, ty, val ' + mklist(initial_value(ty), i→n(i0)), st), 0 ≤ i0, i ≤ i0 ⊦ i = 0, r -- i ' ∈ addarray(r, ty, 1 + i0, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 62:
⊦ is_fskey(sk) ∧ sk ≠ _length ∧ sk ≠ _type → (r -- sk ∈ addarray(r, ty, i, st) ↔ r -- sk ∈ st)
Proof step 69:
¬ (is_fskey(i ') ∧ i ' ≠ _length ∧ i ' ≠ _type), 0 < i0, 0 < i, r -- i ' ∈ addarray(r, ty, val ' + mklist(initial_value(ty), i→n(i0)), st), 0 ≤ i0, i ≤ i0 ⊦ i = 0, r -- i ' ∈ addarray(r, ty, 1 + i0, st)

Rule argument

[crewrite-arg: in-1dim-fskey , F , [st, i, ty, sk, r] → [st, 1 + i0, ty, i ', r] ]
