Abstract
A numerical set is a co-finite subset of the natural numbers that contains zero. Its Frobenius number is the largest number in its complement. Each numerical set has an associated semigroup , which has the same Frobenius number as . For a fixed Frobenius number there are numerical sets. It is known that there is a number close to such that the ratio of these numerical sets that are mapped to is asymptotically . We identify a collection of families of numerical semigroups such that for a fixed the ratio of the numerical sets that are mapped to converges to a positive limit as goes to infinity. We denote the limit as , these constants sum up to meaning that they asymptotically account for almost all numerical sets.
