Those concepts are based on certain symmetries of the gaps of the semigroup with respect to their Wilf number. We prove that the set of supersymmetric and self-symmetric gaps completely determines the semigroup and we compare this set with the fundamental gaps of the semigroup.engjournal articlehttp://www.tandfonline.com/toc/lagb20/currentopen access512512.74Numerical semigroupFrobenius problemG-semimoduleSyzygy.ÁlgebraGrupos (Matemáticas)1201 Álgebra
