Abstract
We establish that the powerset ℘(ℝ) of the real line ℝ, ordered by set-inclusion, has the same ordertype as a certain subset of ℘(ℝ) ordered by homeomorphic embeddability. This is a contribution to the ongoing study of the possible ordertypes of subfamilies of ℘(ℝ) under embeddability, pioneered by Banach, Kuratowski and Sierpiński.
