Its faces include ten small triangles on the top, ten small triangles on the bottom, ten irregular quadrilaterals, and twenty larger triangles. One quadrilateral and two of the large triangles meet at each of the tenpoints around the side. Several faces are coplanar - five of the quadrilaterals are in one plane, five in another plane, and the triangles are four to a plane, This reduces the faces to 2 + 10 or twelve.
