Because of the mathematical content and length of this contribution to Karl's Corner, we are only making
it available as a PDF file. It can then be printed using
Adobe's Acrobat Reader (version 4 and higher). This document is hard to read on screen, because it uses the Computer
Modern fonts from the LaTeX typesetting system that were designed for printing.
