32. Copy circle 23 to the center of lefthand circle 29.
33. Copy circle 11 two times, to the upper intersection of circle 15 and the vertical centerline, and to the intersection of circle 32 and line 28.
34. Construct two parallel lines, tangent to circles 33 at both sides, and extend the righthand one downto the lower line 30.
35. Remove all redundant parts from lines 30, 31 and 34, and create the pattern as shown.
36. Copy pattern 35 eleven times, by repeating all necessary steps with respect to the other angular points 4 (nrs. 1 - 11).
37. Construct a "two-points" circle (defined by the two end-points of a centerline) between the intersections of ray 22 nr. 2 and circles 17 and 19.
