| 4. |
| Construct the inscribed circle of triangle 3. |
| 5. |
| Construct the inscribed hexagon of circle 4, pointing up. |
| 6. |
| Construct the inscribed circle of hexagon 5. |
| 7. |
| Construct the inscribed hexagon of circle 6, pointing up. |
| 8. |
| Construct the inscribed circle of hexagon 7. |
| 9. |
| Construct the inscribed hexagon of circle 8, pointing up. |
| 10. |
| Construct the inscribed circle of hexagon 9. |
| 11. |
| Construct the inscribed hexagon of circle 10, pointing up. |
| 12. |
| Construct the inscribed circle of hexagon 11. |
| 13. |
| Construct the inscribed hexagon of circle 12, pointing up. |
| 14. |
| Construct the inscribed circle of hexagon 13. |
| 15. |
| Construct a circle centered at the top of hexagon 7, tangent to circle 14 at the upper side. |
| 16. |
| Copy circle 15 five times, to the other angular points of hexagon 7. |
| 17. |
| Construct the inscribed hexagon of circle 14, pointing up. |
| 18. |
| Construct the inscribed circle of hexagon 17. |
| 19. |
| Copy circle 18 six times, to the angular points of hexagon 2. |
| 20. |
| Copy circle 15 to the intersection of the righthand side of hexagon 2 and the horizontal centerline. |
| 21. |
| Construct a circle concentric to circle 1, tangent to circle 20 at the righthand side. |
| 22. |
| Construct a circle centered at the upper intersection of circle 21 and the vertical centerline, tangent to circle 10 at the upper side. |
| 23. |
| Copy circle 22 to the center of circle 1. |
| 24. |
| Circles 1, 4, 6, 14, 15, 16, 19, 21, and 23, are used for the final reconstruction. |
| 25. |
| Remove all parts not visible within the formation itself. |
| 26. |
| Colour all areas corresponding to standing... |
| 27. |
| ...or to flattened crop, and finish the reconstruction of the 2020 Yarnbury Castle formation. |
| 28. |
| The final result, matched with the aerial image. |
