Symmetric 2 tensor

Webfrom the tensor. Since the tensor is symmetric, any contraction is the same so we only get constraints from one contraction. The result of the contraction is a tensor of rank r 2 so we get as many components to substract as there are components in a tensor of rank r 2. The total number of independent components Webthese basic symmetries of the SM, but they do not genuinely support the idea of grand unification. However, when combining them in the product group SU(4)=SU(3)⊗U(1), and then by combining all groups into SU(2)⊗ SU(4), one gets a combined symmetry scheme that seems to support unification by the group SU(8). It is found that the smaller
