Too sloppy

This is much too superficial: A symbol is not the same as a tensor. This obscures a very simple abbreviation. --Peter Schmitt 01:40, 2 January 2011 (UTC)

I've modified the wording slightly, and introduced a sub-heading. According to the cited sources, the Levi-Civita symbol also is used to denote the alternating tensor or the completely antisymmetric tensor with three indices in three dimensions.
