E-6 unification model building II. Clebsch-Gordan coefficients of 78 circle times 78

We have computed the Clebsch-Gordan coefficients for the product (000 001)x (000 001), where (000 001) is the adjoint 78-dimensional representation of E-6. The results are presented for the dominant weights of the irreducible representations in this product. As a simple application we express the sin glet operator in 27x78x (27) over bar in terms of multiplets of the Standar d Model gauge group. (C) 2000 American Institute of Physics.
