Imagine that the vertices of a cycle of length $n$ are labelled by the elements $1,\\dots,n$. We are allowed to change this labelling by swapping the labels of any two vertices on the cycle. How many swaps are needed to obtain a labelling that has the elements $1,\\dots,n$ in clockwise order?\n  We provide evidence for their conjecture that at most $n-3$ transpositions are needed to sort a circular permutation when $n$ is not prime.
