Interestingly, pentagon is the only polygon for which number of constructive relationship (number of sides) equals the number of destructive relationship (number of diagonals). This is easily proven since the only solution to the following equation:

is

*n*= 5. Now, it is useful for a computer programmer to introduce a coefficient which can be used to compute the compatibility of any two given

The three numerical values of compatibility coefficient

*c*(namely -1, 0, 1) are to be interpreted as destructive, neutral, and constructive, respectively. A convenient way to compute

_{p}*c*is to use the following equation:

_{p}For example, in the case of wood

*c*(0,1) = 1, a constructive relationship. In the case of fire

_{p}*c*(1,4) = -1, a destructive relationship.
