We present an explicit formula for the transition matrix from the type ₙ Koornwinder polynomials ₍₁ᵣ₎(|, , c, |, ) with one column diagrams, to the type ₙ monomial symmetric polynomials m₍₁ᵣ₎(). The entries of the matrix C enjoy a set of four-term recursion relations. These recursions provide us wi...
