3b. Truncated octahedron 6/4 8/6 from truncation of octahedron 8/3

Data

The distance from the centre of the octahedron to the centre of the triangle is EP× 0.41

The distance from the centre of the truncated octahedron to the centre of the hexagon (red) is EA×1.22. . The two distances are equal, thus E_A = E_P/3.

Construction

The edges are divided in three equal parts.

. The eight hexagons (red) are applied on the original triangles. The six corners (yellow) are cut off ,

resulting in six squares (green-blue).
