In this work we will show that if F is a positive integer, then the set of Arf numerical semigroup with Frobenius number F, denoted by Arf(F), is a covatiety. The previous results will be used to give an algorithm which calculates the set Arf(F). Also we will see that if X ⊆ S\Δ(F) for some S ∈ Arf(F), then there is the smallest element of Arf(F) containing X. %K algorithm %K Arf numerical semigroup %K Arf-sequence %K covariety %K Frobenius number %K multiplicity %K Numerical semigroup %~ Universidad de Cádiz
