For example, if sixteen species are under study, the maximum GA 

 value would be 1600, and the minimum would be 100 (that is, since 

 the PA of species A to species A = 100, and the PA of species A to 

 any other species = 0, the minimum GA value = 100). A third

 of each of 16 taxa to all others. Affinity indices are expressed along 

 the radii from 0% to 100%, beginning at the center. See text
