In this paper, we propose a 2-parameter family of coupled Painlevé II systems in dimension four with affine Weyl group symmetry of type D (2) 3. We also propose a 4-parameter family of 2-coupled D (2) 3-systems in dimension eight with affine Weyl group symmetry of type D In this paper, we present a 2-parameter family of 2-coupled Painlevé II systems with affine Weyl group symmetry of type D
