Diagonal matrix of the tenser product (≡* Dƿ), ƿ ≥ 3 is prime number

Several concepts are presented within this article that will be utilized in the diagonal matrix calculation and compute the (ω ⊗ (≡ * Dƿ), ƿ ≥ 3 is prime number. Where ω ⊗ (≡ * Dƿ) is indicate for the tensor product of the rational character table matrix of dihedral group Dƿ by itself.
