                             ABSTRACT

           It  is  useful in number theory to get identities
      that  express  x  as  sums or differences of k-powers.
      The  main  tool used before was the Tarry-Escott prob-
      lem.   Recently  Vaserstein  extended a formula due to
      Rao  to  get  better identities.  We notice that these
      two  identities are related to permutation groups.  We
      develop  a  theory  that  allows  us to find brand-new
      identities,  for  any  representation  of  any  finite
      group.
