i think this is typically called an epsilon-ball?

Actually, no; it's a collection of points whose epsilon balls form a cover of the space. It's related to the notion of total boundedness, which (along with completeness) gives a characterization of compactness. The article needs some love, though, to explain a little. 96.255.124.117 (talk) —Preceding undated comment added 04:48, 1 May 2012 (UTC).[reply]
