Avoid sites like Chegg or Course Hero for D&F. Many posted solutions contain critical errors, especially in group actions and Sylow proofs. abstract algebra dummit and foote solutions chapter 4
In Section 4.5 (Sylow Theorems), the problems become more computational. When looking for the number of Sylow -subgroups ( ), always check the congruence and the divisibility Recommended Resources for Solutions , a fundamental concept that connects abstract groups

($\Rightarrow$) Suppose $H$ is a subgroup of $G$. Then $H$ is non-empty, and for any $a, b \in H$, we have $a, b^-1 \in H$, which implies $ab^-1 \in H$.
