                             6. Conclusions
                                       A mathematical  device, the NSS,  which can  be  related to  Artificial
                             Intelligence  techniques, has  been  defined and  applied in  order to  solve or reformulate
                             some  quantum chemical  problems. This  symbol is  related to  computer formulae
                             generation. It  has  been  shown  that by means of the  use of NSS’s many  applications of
                             such symbols  can  be  found in  mathematics as  well as  in  Mathematical  Chemistry in
                             particular.

                                       Apart of  being  able to  simplify  typographical  structures, the  NSS symbols
                             constitute the  basic  elements of  a completely  general  framework, allowing  to write
                             mathematical  formulae, in  such a  manner that immediate  translation to any  high  level
                             programming language is feasible, producing a complete general code, which can be kept
                             sequential or parallelized  in a simple manner.
                                       Pedagogical and in many cases mnemotechnical formula structures appear to
                             be also  deduced at  a  very  generic level  as  a  consequence of  the use  of  this  kind of
                             devices.
                                       The obtained mathematical  patterns  seems to  be  also  fairly  well  adapted  to
                             Artificial  Intelligence  formula  writing  programming philosophy.
                                       An assorted  set  of purely  mathematical and  Quantum  Chemical application
                             examples prove  the generalization  power and  flexibility of  this  presently  described
                             symbolic framework.
                                       When NSS’s  together  with  LKD’s are  adopted as  working  tools, both
                             structures  appear to trigger  some  sort of  thinking  machine, in  such a  way  that  once  a
                             given problem  is  solved, new study  areas  immediately  appear to  be  a  promising  future
                             application  field in the  focus of  the  imagination  eye.

                                       One  can  conclude that a robust and powerful theoretical machinery has been
                             described,  possessing general, far reaching imaginative possibilities.

                                       Perhaps there are  hidden in  the  symbolic  limbo  other possible similar tools,
                             even better  than  these  described  here. We are  confident in  that this  paper will  stimulate
                             the research  interest in  this direction.
