Given that the roots {zj} of polynomial Equation (553c) are all on the unit circle and occur in conjugate pairs, show that we must have ϕ2p,2p = −1. For the case p = 2, merge this result with Equation (554b) to form a three-dimensional matrix equation that can be used to solve for ϕ4,1, ϕ4,2 and ϕ4,3.
