The triangular torus, or torapyramid, can be defined as circle # triangle. Since the torus product is not uniquely defined in this case, this makes it an immeasurable rotope. However, CSG Notation defines the triangular torus as a triangle lathed in such a way that the bases of all the triangular radial slices lie in the same plane.
