A cyclosphere is a five-dimensional rotatope constructed from the product of a ball and a disc. This means that it can be considered to be a duoprism with a ball and disc as factors. It is composed of two curved 4-D cells joined by a 3-D surface.
Structure and Sections[]
The cyclosphere's sections come in two types. Either there is a disc expanding to a duocylinder and back, or a ball expanding to a spherinder and back.
