Proof step 4 from proof fits-subset-01 (previous step)

fits(r, sks, st), st ⊆ st0 ⊦ fits(r, sks, st0), junkref(str, r, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 3:
⊦ ¬ junkref(str, r, st) ∧ fits(r, sks, st) ∧ st ⊆ st0 → fits(r, sks, st0)

Rule argument

[x0lemmaarg: spec-name: instance-name: lemma-name: fits-superset antecedent: succedent: ¬ junkref(str, r, st) ∧ fits(r, sks, st) ∧ st ⊆ st0 → fits(r, sks, st0) substlist: [str, r, st, sks, st0] → [str, r, st, sks, st0] add preconditions?: F is rewrite lemma?: T current spec?: T rotate lemma?: F replace all?: T paths: ((1, 0, 0)) dummy: () ]
