If you wished to plant some trees so that each was
equidistant from every other tree, what is the largest number you could plant?
Answer:
Four.
Most people think the answer is three, because it is easy to create an
equilateral triangle with a tree planted on each corner. But if the land had
just the right contours, a fourth tree might be planted in a valley or on a
hill, forming a pyramid shape above or below the centre of the triangle in a
sport that would maintain the equidistance.
