89. The Cantor set, named after the German mathematician
Georg Cantor (1845–1918), is constructed as follows. We start
with the closed interval [0, 1] and remove the
interval
(G,). That leaves the two intervals 0, and , 1 and we
remove the open middle third of each. Four intervals remain
and again we remove the open middle third of each of them.
We continue this procedure indefinitely, at each step removing
