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. Does the rewording meet your approval? John R. Brews 17:29, 2 January 2011 (UTC)
Though the L-C symbol and the L-C tensor are closely related, I think that the advanced topic (tensor) and the elementary one (symbol) should be treated separately. Thus I moved the tensor part.
By the way, common notions (that appear in many sources) need no reference, I would say.
