I believe I read that they make a larger, normal parabolic mirror, and then cut disks out of it. They'd get 4 out of a 10 inch normal mirror. I think if you put 3.6 inch mask on the focuser side of a 10" newt, between the spider vanes, you'd have the same thing basically. I could be totally wrong though.

Interesting. That sounds like a difficult (asymmetric) mirror to produce.
