Look at the construction, its points and its distances. Ratios between distances are what become frequencies.

The complete construction, whatever is shown in the drawing.
Each length divided by the reference length gives a ratio r. These ratios become frequencies in the next step.

m concentric rings of n points (radius R·k/m), alternate rings rotated by π/n, joined to neighbours on adjacent rings.
Symmetry: Dihedral Dn.
Mandala patterns are central to Hindu and Buddhist practice; this is a geometric abstraction.
