Cylindrone (EntityTopic, 11)
From Hi.gher. Space
The cylindrical pyramid is a 4D pyramid with a cylindrical base. It has a single vertex, and is bounded by two cones, a cylinder, and a triangular torus with a zero inner radius (the "hole" is degenerate, a vertex is in its place). Its vertex-first projection into 3D is a cylinder containing two cones that meet at the central vertex.
