5.		Construct the inscribed circle of square 4.
6.		Construct the inscribed square of circle 5, pointing up.
7.		Construct the inscribed circle of square 6.
8.		Construct the inscribed square of circle 7, pointing up.
9.		Construct the inscribed circle of square 8.
10.		Construct the inscribed square of circle 9, pointing up.
11.		Construct the inscribed circle of square 10.
12.		Construct the inscribed square of circle 11, pointing up.
13.		Construct the inscribed circle of square 12.
14.		Construct the inscribed square of circle 13, pointing up.
15.		Construct the inscribed circle of square 14.
16.		Construct the "two-points" circle (defined by the two end-points of a centerline) between the upper intersections of circles 13 and 15 with the vertical centerline.
17.		Copy circle 16 to the top of square 2, and move this circle (copy and delete original) to its own lower intersection with the vertical centerline.
18.		Construct a circle concentric to circle 1, tangent to circle 17 at the lower side.
19.		Copy circles 13 and 15 to the center of circle 17. See detail.
20.		Copy circles 13 and 15 three more times, to the corresponding positions with respect to the other angular points of square 2.
21.		Construct the "two-points" circle between the center of circle 16 and its lower intersection with the vertical centerline.
22.		Copy circle 21 to the top of square 4.
23.		Construct a circle concentric to circle 1, tangent to circle 22 at the lower side. See detail.
24.		Construct the "two-points" circle between the center of circle 22 and its lower intersection with the vertical centerline.
25.		Copy circle 24 four times, to the angular points of square 4. See detail.
26.		Construct two pairs of parallel lines, parallel to the horizontal and vertical centerlines respectively, tangent to circles 25, all at both sides. See detail.
27.		Circles 1, 3, 5, 7, 9, 11, 13, 15, 18, 19, 20, and 23, and lines 26, are used for the final reconstruction.
