| 2. |
| Construct the inscribed equilateral triangle of circle 1, pointing down. |
| 3. |
| Construct the inscribed circle of triangle 2. |
| 4. |
| Construct the inscribed hexagon (regular 6-sided polygon) of circle 3, pointing up. |
| 5. |
| Construct the inscribed circle of hexagon 4. |
| 6. |
| Construct the inscribed hexagon of circle 5, pointing to the right. |
| 7. |
| Construct the inscribed circle of hexagon 6. |
| 8. |
| Construct a circle centered at the intersection of the upper side of triangle 2 and the vertical centerline, passing through the upper righthand angular point of hexagon 6. |
| 9. |
| Copy circle 8 three times, to the angular points of triangle 2. |
| 10. |
| Construct the inscribed equilateral triangle of circle 5, pointing to the right. |
| 11. |
| Construct a circle concentric to the lower circle 9, passing through the lower intersection of circle 7 and the lefthand side of triangle 10. |
| 12. |
| Copy circle 11 two times, to the centers of the other circles 9. |
| 13. |
| Draw three rays of circle 1, to the angular points of triangle 2. |
| 14. |
| Construct a circle centered at the intersection of the upper righthand circle 9 and ray 13, passing through the intersection of circle 11 and ray 13. |
| 15. |
| Copy circle 14 two times, to the corresponding intersections of the other circles 9 and rays 13. |
| 16. |
| Copy circle 14 to the intersection of circle 3 and the upper righthand ray 13. |
| 17. |
| Construct a circle concentric to circle 1, tangent to circle 16 at the upper righthand side. |
| 18. |
| Construct a circle centered at the righthand intersection of circle 7 and passing through the righthand intersection of circle 5, both with the horizontal centerline. |
| 19. |
| Copy circle 18 to the righthand intersection of circle 17 and the horizontal centerline. |
| 20. |
| Construct a circle concentric to circle 1, tangent to circle 19 at the righthand side. |
| 21. |
| Construct a circle, tangent to circle 7 (from the outside), and tangent to the righthand sides of hexagon 6. |
| 22. |
| Copy circle 21 four times, to the centers of circles 1 and 9. |
| 23. |
| Construct three pairs of parallel lines, parallel to rays 13, tangent to circles 22 at both sides. |
| 24. |
| Circles 7, 9, 11, 12, 14, 15, 17, and 20, and lines 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 2018 Keysley Down formation. |
| 28. |
| The final result, matched with the aerial image. |
