6 bands of 6 tori, each with a square cross-section, centered on the great circles with axes through the vertices of a regular icosahedron. These can be created through weaving as well. Buckminster Fuller called this as an "isometric vector matrix grid" with physical properties related to electromagnetic frequencies at the appropriate size (but with 24 bands of no thickness). Thetori comprising the bands are equally spaced at the diameter of a torus, and .8 mm on a side. The centers of the tori meet at the face centers of the associated icosahedron.
