Abstract
The average age difference between pairs of star clusters in the Large Magellanic Cloud (LMC) increases with their separation as the similar to 0.35 power. This suggests that star formation is hierarchical in s pace and in time. Small regions form stars quickly and large regions, which often contain the small regions, form stars over a longer period . A similar result found previously for Cepheid variables is statistic ally less certain than the cluster result.
