These all are scaliform polytera. They even are convex if d=1. – The boundary case n/d=2 not only would provide different incidences than the general matrix given below (degenerate {n/d}-gons), it even itself would become dimensionally degenerate. In fact it happens to be {4} || perp {4}, the hull of which is just hex.
