Sn contains a subgroup of order m, where 1 ≤ m ≤ n.
Sn contains a subgroup of order (n -1)!.
Sn is non-Abelian for all n ∈ N.
There exists a cycle of order m > 1, which belong to Z(Sn).
There exist three transpositions whose product is the identity e of the symmetric group Sn.
The order of the product of two transpositions is either 2 or 3.
If α and β are two disjoint permutations such that αβ = e, then α = β = e.
Every permutation in Sn can be expressed as a product of disjoint cycles.
