Sesquitruncated octahedron

The enneagonal-faced polyhedron is a near-miss Johnson solid. It's faces are 6 squares, 24 isosceles triangle s and 8 regular enneagons.

To construct it, one needs to enscribe an enneagon in every face of regular octahedron and fill all the remaining gaps with triangles and squares.



Alternatively it can be constructed as a truncation of truncated octahedron.
