As you can see immediately, the necessary heptahedron (of Diagram 4) and the necessary seven-fold star (of Diagram 1) actually formed part of the formation in the field. That is, in the form of underlying 'construction lines'. They could clearly be seen in the formation. On most aerial shots they can also well be recognised.

East Field formation

It is far more complicated to construct the East Field formation.

However, with the help of the Tawsmead Copse formation things become much easier. There turns out to be a strong connection between the two formations.

Firstly, one constructs a circle. The centre of this circle is the intersection of the outside of the Tawsmead Copse formation and the radians. The outside of the circle touches the circle that was drawn around the heptahedron in the heart of the Tawsmead Copse formation. Diagram 10 shows how this is done.

Subsequently an identical circle is constructed in the centre of the formation.

Then, another circle is constructed. This one touches the central circle and has as its centre the intersection of the radians and the seven-fold star of Diagram 1.

See Diagram 12.

Note: all circles constructed so far could only be made with the aid of the Tawsmead Copse formation!

These intersections also function as a starting point for the seven-fold star as constructed in Diagram 14.

This seven-fold star crosses the circle of Diagram 12 at two different points.
