Abstract: Let $ I\subset S=\mathbb{K},[x_1,\dots ,x_n]$ be an ideal generated by squarefree monomials of degree $ \ge d$. If the number of degree $ d$ minimal generating monomials is $ \mu _d(I)\le \min (\binom {n}{d+1},\sum _{j=1}^{n-d}\binom {2j-1}{j})$, then the Stanley depth $ \operatorname {sdepth}_S(I)\ge d+1$.
