Proof step 11 from proof path-nodups-subset (previous step)

# H < # x, path(x, H) ⊦ x = [], dups(x)

User applied rule structural induction

And obtained the following new goals

Proof step 10:
∀ H. # H < # x0 ∧ path(x0, H) → x0 = [] ∨ dups(x0), # H < # (r + x0), path(r + x0, H) ⊦ r + x0 = [], dups(r + x0)

Rule argument

[VARWITHVARSEQSARG : x, ()]
