The order of an element $g$ in some group is the least positive integer $n$ such that $g^n = 1$ (the identity of the group), if any such $n$ exists. If there is no such $n$, then the order of $g$ is defined to be $\infty$.

- Determining order of an element in a symmetric group
In mathematics, the order of a finite group is the number of its elements. If a group is not finite, one says that its order is infinite. The order of an element of a group (also called period length or period) is the order of the subgroup generated by the element.
1 kwi 2023 · We'll see the definition of the order of an element in a group, several examples of finding the order of an element in a group, and we will introduce two basic but important...
In group theory, the order of an element is an important property that helps unravel the structure of a group.
15 paź 2014 · A general fact for groups: the order of the product of commuting elements. σ =c1 ⋅ c2 … ⋅cm σ = c 1 ⋅ c 2 … ⋅ c m. is the lowest common multiple of the orders of the ci c i. Consider now the group to be Sn S n and ci c i disjoint cycles therefore commuting. Pairwise commuting factors is essential.
An element $(a,b)\in A\times B$ has order $n$ if and only if $\mathrm{lcm}(\mathrm{order}(a),\mathrm{order}(b)) = n$. Proof. If $(a,b)$ has exponent $n$, then $(1,1) = (a,b)^n = (a^n,b^n)$, so $a^n=1$, $b^n=1$, hence $\mathrm{order}(a)|n$ and $\mathrm{order}(b)|n$.
5 dni temu · The order of an element g of a finite group G is the smallest power of n such that g^n=I, where I is the identity element. In general, finding the order of the element of a group is at least as hard as factoring (Meijer 1996).
