Error

"Any three planes such that no plane is parallel to either of the other two will intersect at a single point" — not at all; take a line and three planes containing this line... Boris Tsirelson 19:14, 4 April 2010 (UTC)

Right, an amazing error. Maybe he means planes with linearly independent normals?--Paul Wormer 08:41, 5 April 2010 (UTC)
This would be a correct formulation. However, is it helpful? The property to have linearly independent normals is not at all simpler than the property to have a single common point. Boris Tsirelson 11:41, 5 April 2010 (UTC)
