abstract = {An integer-valued polynomial on a subset {\$}S{\$} of {\$}\mathbb{\{}Z{\}}{\$} is a polynomial {\$}f(x) \in \mathbb{\{}Q{\}}[x]{\$} with the property {\$}f(S) \subseteq \mathbb{\{}Z{\}}{\$}. This article describes the ring of such polynomials in the special case that {\$}S{\$} is the Fibonacci numbers. An algorithm is described for finding a regular basis, i.e., an ordered sequence of polynomials, the {\$}n{\$}th one of degree {\$}n{\$}, with which any such polynomial can be expressed as a unique integer linear combination.},
