This is a really popular configuration. Why? Because the megahubs are ideally designed for 3V configurations (12 degrees of curvature in each arm X 2 arms per hub X 15 hubs = 360 degrees - voila! A perfect circle) and the struts fit right into the arms of the hubs with little or no persuasion. It is more than twice as strong as the standard configuration, so you can place weight on the top surface of the dome, or hang weight on the inside. The 5/9 means that it is 5/9 of a sphere, so just larger than a hemisphere. That gives you an extra amount of height inside, and the sides bow slightly out before they begin to curve in, meaning you can use the full floor area to stand or sit in.
