## Images

The octagonal prism can also be seen as a tiling on a sphere:

## Use

In optics, octagonal prisms are used to generate flicker-free images in movie projectors.

## In uniform honeycombs and 4-polytopes

It is an element of three uniform honeycombs:

It is also an element of two four-dimensional uniform 4-polytopes:
