26.		Draw four lines, two parallel to rays 3 nrs. 4 and 14, tangent to circles 25 at the lower sides, and two parallel to rays 3 nrs. 6 and 12, tangent to circles 24 and 25 at the upper sides. See detail.
27.		Construct a circle centered at the lower intersection of circle 23 and the vertical centerline, tangent to the central circle 25 at the lower side.
28.		Copy circle 27 to the righthand intersection of circle 1 and the horizontal centerline.
29.		Construct a circle concentric to circle 1, tangent to circle 28 at the lefthand side.
30.		Construct a "two-points" circle between the lower intersections of circles 23 and 27 with the vertical centerline.
31.		Copy circle 30 seventeen times, to the center of circle 1, and to the intersections of circle 11 and rays 3.
32.		Draw sixteen pairs of parallel lines, parallel to rays 3, tangent at both sides to the central circle 31 and the other circles 31, as shown.
33.		Draw the connecting line between the righthand intersections of circles 6 and 20 with the horizontal centerline, and divide this line into five equal parts.
34.		Construct four circles concentric to circle 1, passing through dividing nodes 33. See detail.
