A #SteinerChain is a set of n circles, each tangent to its neighbors and to two given non-intersecting circles. If a closed chain exists, Steiner’s porism guarantees infinitely many.

Their centers lie on an ellipse.

Steiner Chain -- from Wolfram MathWorld
Given two circles with one interior to the other, if small tangent circles can be inscribed around the region between the two circles such that the final circle is tangent to the first, the circles fo...
