If the numerator (4) and denominator (6) or
represented as a square and a hexagon the
beads of the abacus may represent the points at
the vertices of these polygons. Now from a
beginning point or vertex, count clockwise around
the polygons to select points separated by a
number equal the difference between the numerator
and denominator, in this case (2) . The number
of selected points for each polygon will be less
than the number of points of the given polygons
by a common factor. The triangular array of
the abacus coordinates this property of polygons.
