Brunnian link. Presumably the simplest Brunnian link other than the Borromean rings.[1] The second in an infinite series of Brunnian links -- if the blue and yellow loops in the illustration below have only one twist along each side, the result is the Borromean rings; if the blue and yellow loops have three twists along each side, the result is this L10a140 link; if the blue and yellow loops have five twists along each side, the result is a three-loop link with 14 overall crossings, etc.[2]

In a visual form which makes it evident that it is a Brunnian link.
