The subset
of the Euclidean plane formed by the union of
the x-axis, the line
segment with interval
of the y-axis, and the sequence of segments with
endpoints
and
for all positive integers
.
With respect to the relative topology is pathwise-connected.
It is therefore connected, but not locally
pathwise-connected at any point of the open interval
since each open disk centered at point one of these points
intersects
in a union of parallel segments, forming a disconnected set.
