I'll have a look at the documentation for this element.

Within the cube, I know the location of the points of the geometry (based on material data), but I'll have to set up the connectivity to cells myself. Then, I can do what Wolfgang suggested -- create the triangulation using the Triangulation::create_triangulation function -- without recourse to a mesh generator. The problem is, "how to create the connectivity to cells?" That's why I was thinking of excluding unnecessary nodes.
