Proof step 8 from proof cyclic-putbar-04 (previous step)

refs = r + refs0 ∧ refs ≠ [], dups(refs), validrefs(`docs2store', refs, mkclasstype(`java.lang.Object' .class), putByteArray(bytes, r1, i, st)), okbytearray(r1, st) ⊦ r = r1, cyclic(`docs2store', r, st)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 7:
okbytearray(r1, st), validrefs(`docs2store', r ' + refs0, mkclasstype(`java.lang.Object' .class), putByteArray(bytes, r1, i, st)) ⊦ r = r1, cyclic(`docs2store', r, st), ¬ r ∈ refs0 ∧ ¬ dups(refs0)

Rule argument
