symmetries
Indeling
Fatin Uluengin catalogues different patterns of symmetry counting the number of points in the half star in the apex of the muqarnas.
So a 8/2 = 4 stands for a half 8-pointed star in the apex.
plan of the muqarnas
Next picture illustrates how a 8/2=4 type muqarnas can be filled in using figures with angles that are mulpitles of 22.5°.
The number of points of a half star difines the form of the figures that can be used, but it doesn't defines the whole plan of the muqarnas. To illustrate this both halfs of the plan are filled in in two different ways.
