Proof step 10 from proof unchanged-cyclic-equiv (previous step)

unchanged(str, r, st, st0), cyclic(str, r, st0) ⊦ junkref(str, r, st), cyclic(str, r, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 2:
⊦ unchanged(str, r, st, st1) ↔ unchanged(str, r, st1, st)
Proof step 9:
unchanged(str, r, st0, st), cyclic(str, r, st0) ⊦ junkref(str, r, st), cyclic(str, r, st)
