## Abstract

For the family of maps Fλ(z) = z^{n} + λ/z^{n} where n ≥ 3, it is known that there is a McMullen domain surrounding the origin in the parameter plane. This domain is then surrounded by infinitely many “Mandelpinski” necklaces I_{k} for k = 0, 1, 2, …. These are simple closed curves surrounding the McMullen domain and passing through exactly (n − 2)n^{k} + 1 centers of baby Mandelbrot sets and the same number of centers of Sierpinski holes. When n = 2 there is no such McMullen domain in the parameter plane. However, we show in this paper that there do exist Mandelpinski necklaces I^{k} in this case. Now these necklaces converge down to the origin. And, consistent with the formula for higher values of n, each I^{k} passes through the centers of only one Mandelbrot set and one Sierpinski hole.
