AbstractIt is shown that if the prime ideal
$$P(S) \subseteq k[x_1 , \cdots ,x_4 ]$$
,⋯, x4], k an arbitrary field, has generic zero xi=tni, ni positive integers with g.c.d. equal l, l ≤ i ≤ 4, then P(S) is a set-theoretic complete intersection if the numerical semigroup S= is symmetric (i.e. if the extension of P(S) in k[[x1,⋯, x4]] is a Gorenstein ideal).
