  Let $I\supsetneq J$ be two squarefree monomial ideals of a polynomial algebra
over a field generated in degree $\geq d$, resp. $\geq d+1$ . Suppose that $I$
is either generated by three monomials of degrees $d$ and a set of monomials of
degrees $\geq d+1$, or by four special monomials of degrees $d$. If the Stanley
depth of $I/J$ is $\leq d+1$ then the usual depth of $I/J$ is $\leq d+1$ too.
