Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. The octagonal bipyramid is one of the infinite set of bipyramids, dual to the infinite prisms. If an octagonal bipyramid is to be face-transitive, all faces must be isosceles triangles. However, there is a rather odd-looking version of the octagonal bipyramid with each of the faces congruent having a right scalene triangle as the shape of the faces.
