We present some solutions of the set-theoretic parametric Yang-Baxter equation. These solutions are birational maps with several invariants and a Lax representation[4]. We show that we can use these maps as building blocks in order to construct higher dimensional birational maps which have nice properties and we prove their integrability in the Liouville sense. These maps can be seen as higher dimensional generalisations of the famous integrable QRT maps [3], known as Adler’s Triad maps[1]. Finally, we discuss some new generalisations [2].
