Summary
[edit]| Description | Two trefoil knots (with three internal self-crossings each), shaped somewhat like valknut symbols, mutually interlaced in an ornate way, so that there are 30 total crossings in the overall structure. According to the color-coding in the image, there are three crossings of red over red, three blue-over-blue, 12 red-over-blue, and 12 blue-over-red. |
