摘要：

The "Love Knot" is a little brooch made out of three interlocking circular arcs; an image is incorporated in the familiar Venn diagram of three circular discs in the plane. The Love Knot offers a thread upon which to hang a little minuet between invertibility of the factors of a product, and concepts of "exactness".
