Double Buckethandle

The Cantor 1/5-discontinuum C5 is created using the procedure of deleting the second and the fourth segments from five equal segments (instead of the middle third for the Cantor Ternary Set). C5 is the set of the reals in the unit interval which can be represented without 1-s and 3-s in the form

\begin{displaymath}
\sum _{n=1} ^\infty \frac{a_n}{5^n} \quad .
\end{displaymath}

The Double Buckethandle continuum is the union of: (i) the half circles in the lower plane going through points of $C_5 \cap \{x : 2/5^{n+1}
\le x \le 1/5^n\}$ with the centre $7/10\cdot 5^n$, (ii) the half circles in the upper plane going through points of $C_5 \cap \{x : 2/5^{n+1}
\le 1-x \le 1/5^n\}$ with the centre $1-7/10\cdot
5^n$.

We can find more in [55, p.205 - p.206].
