Here is one more beaded structure defined by the same net similar to that in the previous post except that we use compounded bonds (three beads for a single bond).
This beautiful triple-stranded helically-coiled CNT was made by Chuang last year. We have trouble to fix the relative position among these three strands. That is why I did post the scan for this object. It is apparent from the following scan the spaces between them are still different.
