Plucker basis vectors

6-D vectors are routinely expressed in Plucker coordinates; yet there is almost no mention in the literature of the basis vectors that give rise to these coordinates. This paper identifies the Plucker basis vectors, and uses them to explain the following: the relationship between a 6-D vector and its Plucker coordinates, the relationship between a 6-D vector and the pair of 3-D vectors used to define it, and the correct way to differentiate a 6-D vector in a moving coordinate system
