Query: Tangent Cone of Numerical Semigroup Rings of Embedding Dimension Three   In this paper, we give new characterizations of the Buchsbaum and
Cohen-Macaulay properties of the tangent cone $\gr_\frakm(R)$, where
$(R,\frakm)$ is a numerical semigroup ring of embedding dimension 3. In
particular, we confirm the conjectures raised by Sapko on the Buchsbaumness of
$\gr_\frakm(R)$.
