A higher order Painlevé system of type
was introduced by Y. Sasano. It is an extension of the sixth Painlevé equation (PVI) for the affine Weyl group symmetry. It is also expressed as a Hamiltonian system of order 2n with a coupled Hamiltonian of PVI. In this article, we discuss a derivation of this system from a Drinfeld–Sokolov hierarchy.
