Strickland, Robert W; Not sure;

This cut is a tetrahedron with bulging sides divided into triangles. It has four nearly identical faces. Any of them can be the "top," and any apex can be the "bottom." Use the same angles for any material. Step 2 will determine the size. From the culet to the meet point of 1-1-2-2 is 0.157W.
