(where (Formula presented.), (Formula presented.), (Formula presented.), where (Formula presented.) and (Formula presented.) are positive integers and (Formula presented.)) each raised to an arbitrary non-negative integer power. A (Formula presented.) -comb is a tile composed of m rectangular sub-tiles of dimensions (Formula presented.) separated by gaps of width g. The interpretation is used to give combinatorial proof of new convolution-type identities relating (Formula presented.) for the cases q = 2, (Formula presented.), (Formula presented.), (Formula presented.) for M = 0, m to the permanent of a (0,1) Toeplitz matrix with 3 nonzero diagonals which are (Formula presented.), M−1, and m above the leading diagonal. When m = 1, these identities reduce to ones connecting the Padovan and Narayana's cows numbers.MathematicsArticleSCOPUS10.1080/03081087.2022.21079792-s2.0-8513557299715635139
