Sesquitruncated triangular bipyramid

The sesquitruncated triangular bipyramid is a near-miss Johnson solid. Its faces are 6 isosceles triangles, 2 triangles and 6 mirror-symmetric octagons.

To construct it, one needs to inscribe a mirror-symmetric octagon in each face of a triangular bipyramid and fill all the remaining gaps with regular triangles, isosceles triangles and rectangles.



The sesquitruncated triangular bipyramid can form a near-miss CRF honeycomb with triangular prisms and triangular antiprisms.
