15-15 X16 Seed Flattened Dome.

The 15-15 X16 seed of this flattened dome displays 16-fold symmetry. As a result when it is expanded with the Ray Motif it has a total of 4 distinct rays, in contrast to the Traditional Dome which only has 2 rays as shown here. Instead of the normal top facing the center, The #15 tiles are rotated 90° and all 32 join at the flat dome’s center on their outermost, vertically central vertices.

15 X 11.25° = 168.75°
15 X 11.25° = 168.75°

15-15 X16: Top & Bottom Views

I include four views, 2 top and 2 bottom, of the Chrysanthemum ceiling. This is because it has an unusual shape along with the other seeds of flattened domes. This 15-15 X16 seed is a deeply folded form. Flattened mogharnas / muqarnas domes develop out from the center in ‘waves’ of fixed height per type. The additional tiers of flattened domes are in integral multiples of the central flattened dome’s height.
