    Description

    The four tiles A, B, C, K, using the zometool colored rods.
    Subdivision of the four tiles.
    Three levels of subdivision applied to each of the four tiles A, B, C, K.

    Danzer tetrahedra are joined around blue (90 degrees) edges to obtain four octahedra, each with four copies of tiles A, B, C and with eight copies of tile K. Octahedra <A> and <B> are not convex. the blue edges and all faces adjacent to blue edges are removed.

    30 copies of the octahedron <K> sharing a common vertex can be joined to obtain a complex spiked polyhedron.
    Two levels of subdivision are applied to the above aggregate of K tiles.
    Three levels of subdivision, then only full 4A, 4B, 4C, 8K are displayed with textured faces.
