WebIn group theory, the term order is used in two closely related senses: . the order of a group is its cardinality, i.e. the number of its elements;; the order of an element a of a group is the smallest positive integer m such that a m = e (where e denotes the identity element of the group, and a m denotes the product of m copies of a).If no such m exists, we say that a … WebSo, a group holds four properties simultaneously - i) Closure, ii) Associative, iii) Identity element, iv) Inverse element.

WebLagrange theorem states that in group theory, for any finite group say G, the order of subgroup H (of group G) is the divisor of the order of G i.e., O (G)/O (H).
