Investigations of Higher Order Links
  The following is an amalgamation of four preprints and some computer programs which together represent the current state of our investigations of higher order links. This investigation was motivated by questions discussed and raised in the first author's paper "New States of Matter Suggested by New Topological Structures". An important motivation has been to suggest the synthesis of new types of molecules (see the relevant articles listed in the bibliography). This discussion is not final, but we think that the results and methods are worth making public and would be useful for other investigators.
