We give a description of a possible row-factorization (RF) matrix for each pseudo-Frobenius element of H. Further, when H is symmetric and has embedding dimension four or five, we prove that the defining ideal is minimally generated by RF-relations.falseAlmost arithmetic numerical semigroup | pseudo-Frobenius elements | row-factorization matrixArticle1275-13051 November 20221arJournal2WOS:000848577500001
