no assumptions
Assuming the claims on the left, the claim on the right holds — checked by the archive's pipeline. Proof code is not displayed here.
Description
The complete lift of an independent set is independent.
Proof strategy
Copies of a common original vertex have no edge between them. For different original vertices, independence follows from independence of the original set.
