This tensegrity is quite special to me. It contains only four struts and ten strings and it forms a perfect tetrahedron. It looks very simple and in fact it is, but nevertheless I never saw it before. I have seen perfect tetrahedrons before but in these cases the struts touched eachother or the structure contained fifteen strings. I guess this tensegrity is another example of "less is more".
The tensegrity below is known as a tetrahedron but is in fact a twisted truncated tetrahedron.
