Re: [math-fun] Oddball recurrence problem

If I can't stump the list with sequences, I shall try with chains. The classical (closed) Steiner chain comprises a small frontier circle inside a larger one, with a finite consecutively-touching cyclic sequence of circles occupying the annulus between, each also touching both frontiers. Is it possible for all circles (including both frontiers) of some (real, non-limiting, non-degenerate) chain to lie external to one another? WFL
