| 4. |
| Construct the inscribed equilateral triangle of circle 3, pointing up. |
| 5. |
| Construct the inscribed circle of triangle 4. |
| 6. |
| Construct the circumscribed equilateral triangle of circle 3, pointing up. |
| 7. |
| Construct a circle concentric to circle 1, passing through the intersection of the righthand side of triangle 6 and the horizontal centerline. |
| 8. |
| Construct the inscribed equilateral triangle of circle 5, pointing up. |
| 9. |
| Construct a circle concentric to circle 1, passing through the intersection of the righthand side of triangle 8 and the horizontal centerline. |
| 10. |
| Copy circle 9 to the top of triangle 2. |
| 11. |
| Construct a line, parallel to the vertical centerline, tangent to circles 9 and 10 at the righthand sides. |
| 12. |
| Construct a circle centered at the top of triangle 2, passing through the intersection of line 11 and circle 7. |
| 13. |
| Copy circle 12 two times, to the other angular points of triangle 2. |
| 14. |
| Construct a circle centered at the intersection of the righthand side of triangle 4 and the horizontal centerline, passing through the intersection of the lower side of triangle 8 and the vertical centerline. |
| 15. |
| Copy circle 14 to the center of circle 1. |
| 16. |
| Construct a circle centered at the upper intersection of circle 3 and the vertical centerline, tangent to circle 7 at the upper side. |
| 17. |
| Copy circle 16 to the upper intersection of circle 12 and the vertical centerline. |
| 18. |
| Construct a circle concentric to circle 1, tangent to circle 17 at the upper side. |
| 19. |
| Construct the inscribed circle of triangle 8. |
| 20. |
| Copy circle 19 to the upper intersection of circle 18 and the vertical centerline. |
| 21. |
| Construct a circle concentric to circle 1, tangent to circle 20 at the upper side. |
| 22. |
| Construct a circle centered at the lefthand intersection of circle 14 and the horizontal centerline, tangent to circle 9 at the lefthand side. |
| 23. |
| Construct a circle concentric to circle 1, tangent to circle 22 at the righthand side. |
| 24. |
| Copy circle 23 to the top of triangle 2. |
| 25. |
| Construct a line, parallel to the vertical centerline, tangent to circles 23 and 24 at the righthand sides. |
| 26. |
| Copy lines 11 and 25, while mirroring with respect to the vertical centerline. |
| 27. |
| Repeat steps 11 and 25 (and all the necessary other steps) two times, with respect to the other two angular points of triangle 2, as shown. |
| 28. |
| Circles 3, 5, 12, 13, 15, 18, and 21, and lines 11, 25, 26, and 27, are used for the final reconstruction. |
| 29. |
| Remove all parts not visible within the formation itself. |
| 30. |
| Colour all areas corresponding to standing... |
| 31. |
| ...or to flattened crop, and finish the reconstruction of the 2018 Coneybury Hill formation. |
| 32. |
| The final result, matched with two aerial images. |
