The diagram uses seven roots. Cyan vertices form a regular heptagon; the green radius highlights successive roots, starting with the gold radius at . The short gold arc marks the angle between neighbors. Every highlighted vertex still has seventh power .图中取七个单位根。青色顶点构成正七边形，绿色半径依次指向各个根；起点 由金色半径标出，短金弧表示相邻两根的夹角。无论点亮哪个顶点，它的七次方都等于 。
