Proof step 18 from proof validstatfields-subset (previous step)

¬ (validstatfield(str, sk, st) ∧ st ⊆ st0 ∧ initdone(sk .fs .class, st0) ∧ initdone(sk .fs .class, st)), validstatfields(str, st), st ⊆ st0, init(str, st), init(str, st0), sk ∈ statfields(class), initdone(class, st0), tdname∃(str, class) ⊦ validstatfield(str, sk, st0)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 17:
validstatfields(str, st), st ⊆ st0, init(str, st), init(str, st0), sk ∈ statfields(class), initdone(class, st0), tdname∃(str, class) ⊦ validstatfield(str, sk, st0), validstatfield(str, sk, st) ∧ initdone(sk .fs .class, st0) ∧ initdone(sk .fs .class, st)
