Let $G$ be a finite group. Fix a prime divisor $p$ of $|G|$ and a Sylow $p$-subgroup $P$ of $G$, let $d$ be the smallest generator number of $P$ and ${\cal M}_{d}(P)$ denote a family of maximal subgroups $P_{1}, P_{2}, \ldots, P_{d}$ of $P$ satisfying $\bigcap_{i=1}^{d}P_{i}=\Phi(P)$, the Frattini subgroup of $P$. In this paper, we shall investigate the influence of $s$-conditional permutability of the members of some fixed ${\cal M}_{d}(P)$ on the structure of finite groups. Some new results are obtained and some known results are generalized.
