In optics, octagonal prisms are used to generate flicker-free images in movie projectors.
It is an element of three uniform honeycombs:
Truncated square prismatic honeycomb |
Omnitruncated cubic honeycomb |
Runcitruncated cubic honeycomb |
It is also an element of two four-dimensional uniform polychora: the omnitruncated tesseract and runcitruncated tesseract.
