Indecomposable set-theoretical solutions to the Yang--Baxter equation on a set of size $pq$

Let $p$ and $q$ be different prime numbers. Using recent results of Cedó and Okniński, we describe isomorphism classes of indecomposable set-theoretic solutions to the Yang--Baxter equation of cardinality $pq$.
