Doo-Sabin mesh subdivision using Blender Geometry Nodes

Doo-Sabin mesh subdivision based on a generalization of bi-quadratic uniform B-splines, as opposed to the more commonly used Catmull-Clark subdivision, which is based on generalized bi-cubic uniform B-splines. We can create a Doo-Sabin mesh subdivision using Blender Geometry Nodes with just two nodes.
