Comments:
 
Two students had some problems with this assignment, due to an incorrect
answer in part a. Because of this, the results for the rest of the
assignment were incorrect, although for the most part consistent with the
mistake. One reasson for this problem could be a confusion between right
handed and left handed systems, which is easy to do. The best paper
contains a good explanation for all but the first part, which is not
explained adequately and correctly on any of the papers.
 
GRADER'S COMMENT:  Part (c) can be answered more efficiently using the 
concept of "cyclic permutation".
