What is unusual about the star system TYC 7037-89-1?

A recently discovered and spectacular six-star system, TYC 7037-89-1, possesses a gravitational complexity worthy of Rube Goldberg. Three separate pairs of stars orbit each other in typical binary fashion. But two of these pairs also orbit one another. The third pair, at a greater distance, orbits the other two pairs – the stars in each binary eclipse each other in turn from our point of view.
