A group is a non-empty set $G$ with one binary operation that satisfies the following axioms (the operation being written as multiplication): 1) the … In mathematics, a group is a non-empty set and an operation that combines any two elements of the set to produce a third element of the set, in such a way that the operation is associative, an identity element exists and every element has an inverse. These three axioms hold for number systems and many … See more First example: the integers One of the more familiar groups is the set of integers • For all integers $${\displaystyle a}$$, $${\displaystyle b}$$ and $${\displaystyle c}$$, … See more Basic facts about all groups that can be obtained directly from the group axioms are commonly subsumed under elementary group theory. For example, repeated applications of the associativity axiom show that the unambiguity of Uniqueness of … See more When studying sets, one uses concepts such as subset, function, and quotient by an equivalence relation. When studying groups, one uses … See more A group is called finite if it has a finite number of elements. The number of elements is called the order of the group. An important class is the symmetric groups $${\displaystyle \mathrm {S} _{N}}$$, the groups of permutations of $${\displaystyle N}$$ objects. … See more The modern concept of an abstract group developed out of several fields of mathematics. The original motivation for group theory was the quest for solutions of polynomial equations of degree higher than 4. The 19th-century French mathematician Évariste Galois, … See more Examples and applications of groups abound. A starting point is the group $${\displaystyle \mathbb {Z} }$$ of integers with addition as group operation, introduced above. If … See more An equivalent definition of group consists of replacing the "there exist" part of the group axioms by operations whose result is the element that must exist. So, a group is a set See more
