A note on half of some MED semigroups of maximal or almost maximal length

Abstract

: In this study, we have shown that numerical semigroups M = < 3 , C + 1 , C + 2 > and M = < 3 , C, C + 2 > have maximal or almost maximal length, with conductor C , where C ≡ 0(3) and C ≡ 2(3) , respectively. We also examined whether half of these numerical semigroups were of maximal or almost maximal length.
