Abstract: Using combinatorial methods, we prove the following theorem on the group $ S$ of all permutations of a countably-infinte set: Whenever $ p \in S$ has infinite support without being a fixed-point-free involution, then any $ s \in S$ is a product of three conjugates of $ p$. Furthermore, we present uncountably many new conjugacy classes $ C$ of $ S$ satisfying that any $ s \in S$ is a product of two elements of $ C$. Similar results are shown for permutations of uncountable sets.
