This is a simplified form of the 30-gon that appears on page 90 of Stewart's book (2nd edition) [I finally got a copy!]. This ring is exact. The form presented here differs from Stewart's in that it simply uses prisms and doesn't fret that many faces are coplanar.
This ring is the basis for the Curved Triangle Using 30-gon Circle Arcs.
