skew

a skew arch

Through the given point there are two lines one of which is parallel to one of the given skew lines, while the other is parallel to the other of the given skew lines. These two "parallels" determine a plane, and the only plane, that is parallel to both the given skew lines.

A slope value over 1 indicates that digits are skewer than the Benford condition in favor of low ones. A slope value less than 1 indicates that digits are less skewed as compared with the Benford condition.
