We also show how to use the triadic odometer augmented with plus and minus signs to track octagons. In this and the following figures, rectangles represent algorithmic modules, octagons represent knowledge intensive modules, and rounded rectangles represent integrated modules. The first consists of a countable union of disjoint open periodic islands, each of which is an open octagon. We define the generation number of an actual vertex as the generation of the smallest octagon of which it is a vertex. An important subset of is the set of vertices of octagons which is the same as the set of dart tips. The western face of the octagon is occupied by a tall round-headed arch belonging to the original structure. Each octagon is translated and rotated through the angle - /4 by the transformation. It is generally assumed that the remaining six sides of the original octagon all contained tall round-headed niches of semicircular plan. The generation number of the two next largest octagons is zero. We consider an invariant subset generated by vertices of octagons. Whether they were asked which octagon was brighter, which was darker, or which they liked more, participants tended to select the old one. From the previous results, we can see that the sum of first two terms produces an octagon and last term a parallelogram. The triangle is favoured because it offers a greater possible richness of association than other base-figures, such as square, hexagon, octagon, or decagon. The generation number of the central octagon is -1. These examples are from corpora and from sources on the web.
