Abstract
A practical number is a positive integer such that all positive integers less than can be written as a sum of distinct divisors of . Leonetti and Sanna proved that, as , the central binomial coefficient is a practical number for all positive integers but at most exceptions. We improve this result by reducing the number of exceptions to , where is a constant.
