The mirror itself is composed of 91 hexagonal segments, a segmented mirror design like the Keck telescopes.

In the case of the Keck each of the primary mirrors is composed of 36 hexagonal segments that work together as a single unit.

Blunt, short, spike-like lumps protrude from each point of its hexagonal segments.

The sail-snake was a long tube assembled from the same repeating hexagonal segments.

Later the number of segments was increased to a total of 36 hexagonal segments fully controlled by an active optics control system, working together as a reflective unit.

Instead, he and other experts developed a composite mirror consisting of 36 hexagonal segments, each one 6 feet across and separated from its neighbors by spaces 3 millimeters wide.

As the article said, the mirror has 36 hexagonal segments, not 37.

It is made up of elongated hexagonal segments mounted on a multiple pantograph system, which enables it to "open up" or spread apart vertically as an effect during the concerts.

The ceiling of the concert hall consists of 800 hexagonal segments that can be raised or lowered to change the acoustics of the hall.

The primary mirror for the 39.3 metre design will be composed of 798 hexagonal segments, each 1.45 meters across but only 50 mm thick.
