Proof step 7 from proof Comp-get-02 (previous step)

getarray(r1, i1, j, st) = getarray(r2, i2, j, st), 0 ≤ i, i < j, 0 < j ⊦ st[r1 -- (i1 + i) '] = st[r2 -- (i2 + i) ']

User applied rule insert lemma

And obtained the following new goals

Proof step 3:
⊦ ¬ arraycomp(r1, i1, r2, i2, j, st) → getarray(r1, i1, j, st) ≠ getarray(r2, i2, j, st)
Proof step 6:
¬ arraycomp(r1, i1, r2, i2, j, st) → getarray(r1, i1, j, st) ≠ getarray(r2, i2, j, st), getarray(r1, i1, j, st) = getarray(r2, i2, j, st), 0 ≤ i, i < j, 0 < j ⊦ st[r1 -- (i1 + i) '] = st[r2 -- (i2 + i) ']

Rule argument

[LEMMAARG : Comp-get, [r1, i1, r2, i2, j, st] → [r1, i1, r2, i2, j, st]]
