Each of these conjunction-forms has one smaller circle and two larger, equal-diameter circles. Forms in each horizontal row have the same combinations of proximity, tangency, and/or intersection. Multiple forms in a row differ by whether the smaller, tangent circle is located inside or outside the larger circle(s). The three smaller conjunction-forms in the lowest two rows show “coincident-point” forms, in which multiple contacts occur at a common point. For example, the right-hand form in the bottom row shows tangency of the two larger circles and intersection with the smaller circle occurring at the same point.

In this artwork, each conjunction-form has one large-, one medium-, and one small-diameter circle. The 17 forms comprise two complete subsets from the larger form-set : twelve “double-enclosure” forms (the small and medium circles are enclosed by the large circle) and five “nested” forms (the small circle is enclosed by the medium circle, which is enclosed by the large circle). Five of the six arcs hold one distinct combination of proximity, tangency, and/or intersection, and one of the six arcs (the narrowest arc, fourth from the lower left) holds two combinations : two tangencies + one proximity, and one tangency + two proximities. The multiple forms in each arc are distinct configurations of the combination.
