math. 1. A set of points, no two of which are touching, but each of which is a limit point of other points in the set.
2. the Cantor middle-thirds set: A set of points on a line segment that is the result of an infinite number of steps, in which each step consists of removing the middle-third of the segment(s) remaining from the previous step. It has a Hausdorff dimension of 0.631:step 0: _________________________________________________________________________________ step 1: ___________________________ ___________________________ step 2: _________ _________ _________ _________ step 3: ___ ___ ___ ___ ___ ___ ___ ___ step 4: _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ (etc.)
A Cantor set has an infinite ("uncountable") number of points, the same number as a line segment or any other continuum. However (and paradoxically, by the intuition of Cantor's time) it has zero Lebesgue measure.
