Abstract: The row first-plus-rlast r-right (RFPrLrR) circulant matrix and row last-plus-rfirst r-left (RLPrFrL) circulant matrices are two special pattern matrices. On the basis of the beautiful properties of famous numbers and the inverse factorization of polynomial, we give the exact determinants of the two pattern matrices involving Jacobsthal, Jacobsthal-Lucas, Perrin and Padovan numbers.
