Proof step 6 from proof copy-in-01 (previous step)

r1 ∈ arraycopy(r, i, r0, i0, j, st) ⊦ r1 = r0, r1 ∈ st

User applied rule induction

And obtained the following new goals

Proof step 5:
r1 ∈ arraycopy(r, i, r0, i0, j, st), ∀ j0, r1, r, i, r0, i0, st. i→n(j0) < i→n(j) → (r1 ∈ arraycopy(r, i, r0, i0, j0, st) → r1 = r0 ∨ r1 ∈ st) ⊦ r1 = r0 ∨ r1 ∈ st

Rule argument

[INDHYPARG : [STANDARDINDUCTIONTYPE : ], true, false, i→n(j), [] → [], <]
