Question: Imagine you have ten trees to plant. You have to get an orchard
which must consist of five straight rows of trees and each row must
contain four trees. One straight line of ten trees cannot be used.
Thus the question is: what template could be used for the planting?

Solution: To plant an orchard of five rows of four trees each you could use a
five-point star template as shown in the illustration.
