Theorem spthsfval 29552
Description: The set of simple paths (in an undirected graph). (Contributed by Alexander van der Vekens, 21-Oct-2017.) (Revised by AV, 9-Jan-2021.) (Revised by AV, 29-Oct-2021.)
Assertion
Ref Expression
spthsfval (SPathsβ€˜πΊ) = {βŸ¨π‘“, π‘βŸ© ∣ (𝑓(Trailsβ€˜πΊ)𝑝 ∧ Fun ◑𝑝)}
Distinct variable group:   𝑓,𝐺,𝑝

Proof of Theorem spthsfval
Dummy variable 𝑔 is distinct from all other variables.
