DESCRIPTION:Solution of the Heisenberg spin chain s=1/2 (spectrum of the en
 ergy operator and its eigenvectors) is related with three algebras: the Lie
  algebra sl(2)\, group algebra of symmetric group S_N and an infinite dimen
 tional Hopf algebra\, Yangian Y(sl(2)). Using representaions of these algeb
 ras there are generalization of this model to higher spins s=1\, 3/2\, 2\, 
 ...However there is also possibility to geberalize these algebras preservin
 g structure of their representations. In particular the group algebra of S_
 N will be substituted by the Temperle -- Lieb algebra.
