In a set of overlapping Trees of Life, the lowest one is made up of 80 yods when its 19 triangles are turned into tetractyses. The 94 triangular sectors of the two sets of seven enfolded polygons have 80 corners. Transforming the Tree of Life to the lowest of a sequence of overlapping Trees of Life adds 10 yods. They correspond to the 10 corners of sectors that are not corners of polygons.
