Authors’ abstract: The tensor products of all pairs of the eight fundamental representations of the simple Lie algebra of type \(E_8\) are decomposed into the direct sums of irreducible representations. Simultaneously the tensor products of pairs of Weyl group orbits of fundamental weights are decomposed into the direct sums of irreducible orbits. Both decompositions are presented in the same table.
