Abstract Kitaev et al.(2019) described how to shorten universal words for permutations, to length n!+ n− 1− i (n− 1) for any i∈[(n− 2)!], by introducing incomparable elements. They conjectured that it is also possible to use incomparable elements to shorten universal cycles for permutations to length n!− i (n− 1) for any i∈[(n− 2)!]. In this note we prove their conjecture. The proof is constructive, and, on the way, we also show a new method for constructing universal cycles for permutations.
