Order of an element divides order of group
WitrynaNo, it's not a typo: the order of an element need not be equal to the order of the group (think about e.g. the unit element $e$), it's enough that it divides it Witryna(c) Corollary: In a nite cyclic group the order of an element divides the order of a group. Proof: Follows since every element looks like g kand we have jg jgcd(n;k) = n. QED Example: In a cyclic group of order 200 the order of every element must divide 200. In such a group an element could not have order 17, for example.

j: Corollary (2) Let jaj= n:Then ai = aj if and only if gcd(n;i) = gcd(n;j) and WitrynaTheorem 1.1.1 (Lagrange’s Theorem) The order of a subgroup of a group G divides the order of G. The term “order” is also used with a different, though related, meaning in group theory. The order of an element a of a group G is the smallest positive integer m such that am = 1, if one exists; if no such m exists, we say that a has infinite ...

WitrynaLagrange theorem is one of the central theorems of abstract algebra. It states that in group theory, for any finite group say G, the order of subgroup H of group G divides the order of G. The order of the group represents the number of elements. This theorem was given by Joseph-Louis Lagrange. In this article, let us discuss the …
