The **octagonal diorthoprism** or **odop**, also called **square-octagonal plus-prism** or **sople**, is a uniform compound polychoron. It is a compound of two square-octagonal duoprisms.

It can be edge-inscribed into sidpith.

## Vertex coordinates[edit | edit source]

The vertices are the same as those of its hull, sidpith.
