Hypothesis

Ref	Expression
clwwlknon.v	⊢ 𝑉 = (Vtx‘𝐺)

Assertion

Ref	Expression
clwwlknonOLD	⊢ ((𝑋 ∈ 𝑉 ∧ 𝑁 ∈ ℕ0) → (𝑋(ClWWalksNOn‘𝐺)𝑁) = {𝑤 ∈ (𝑁 ClWWalksN 𝐺) ∣ (𝑤‘0) = 𝑋})

Distinct variable groups:   𝑤,𝐺   𝑤,𝑁   𝑤,𝑋

Allowed substitution hint:   𝑉(𝑤)

Proof of Theorem clwwlknonOLD

Dummy variables 𝑛 𝑣 are mutually distinct and distinct from all other variables.
