Circles on the Rim, 3: Iteration

Iterating on the rim. To iterate, I could reproject the starting figure to a problem which is already solved. But of course I could also back up and treat the whole problem as "intersect conics with circle centers as common foci," in which case the problem is solved before I started. I would like slightly more than this. I want iteration rules, either in the original figure, or in a single projection space. _________________ The Tangent Circle Problem: [list] [*]1.
