Proof step 1 from proof step-L1-L7 (conclusion) (back to tree)

System applied rule normalize

And obtained the following new goals

• Proof step 2:

Rule argument

Additional information

Used simplifier rules: pcstepf-L1: ⊦ pcstepf(gs, ls, L1, a) = (gs.gspmx ≠ ∅ ⊃ L2;L8); disj-13: ⊦ L7 ≠ L2; disj-58: ⊦ L8 ≠ L7;
