    "abstract": "The article is devoted to the describtion of quasitriangular structures\n(universal R-matrices) on cocommutative Hopf algebras. It is known that such\nstructures are concentrated on finite dimensional Hopf subalgebras. In\nparticular, quasitriangular structure on group algebra is defined by the pairs\nof normal inclusions of an finite abelian group and by invariant\nbimultiplicative form on it. The structure is triangular in the case of\ncoinciding inclusions and skewsymmetric form. The nonstandart\n$\\lambda$-structure on the representation ring of finite group, corresponding\nto the triangular structure on group ring, is described.",
