Mathematics
Mathematics (from Greek: ) includes the study of such topics as numbers (arithmetic and number theory), formulas and related structures (algebra), shapes and spaces in which they are contained (geometry), and quantities and their changes (calculus and mathematical analysis, analysis). There is no general consensus about its exact scope or epistemology, epistemological status. Most of mathematical activity consists of discovering and proving (by pure reasoning) properties of mathematical object, abstract objects. These objects are either abstractions from nature (such as natural numbers or "a line (mathematics), line"), or (in modern mathematics) abstract entities that are defined by their basic properties, called axioms. A proof (mathematics), proof consists of a succession of applications of some inference rule, deductive rules to already known results, including previously proved theorems, axioms and (in case of abstraction from nature) some basic properties that are conside ...

Permutation
In , a permutation of a is, loosely speaking, an arrangement of its members into a or , or if the set is already ordered, a rearrangement of its elements. The word "permutation" also refers to the act or process of changing the linear order of an ordered set. Permutations differ from s, which are selections of some members of a set regardless of order. For example, written as s, there are six permutations of the set , namely (1, 2, 3), (1, 3, 2), (2, 1, 3), (2, 3, 1), (3, 1, 2), and (3, 2, 1). These are all the possible orderings of this three-element set. s of words whose letters are different are also permutations: the letters are already ordered in the original word, and the anagram is a reordering of the letters. The study of permutations of s is an important topic in the fields of and . Permutations are used in almost every branch of mathematics, and in many other fields of science. In , they are used for analyzing s; in , for describing states of particles; and in , fo ...

List Of Finite Simple Groups
In mathematics, the classification of finite simple groups states that every Finite group, finite simple group is cyclic group, cyclic, or alternating group, alternating, or in one of 16 families of groups of Lie type, or one of 26 sporadic groups. The list below gives all finite simple groups, together with their order (group theory), order, the size of the Schur multiplier, the size of the outer automorphism group, usually some small group representation, representations, and lists of all duplicates. Summary The following table is a complete list of the 18 families of finite simple groups and the 26 sporadic simple groups, along with their orders. Any non-simple members of each family are listed, as well as any members duplicated within a family or between families. (In removing duplicates it is useful to note that no two finite simple groups have the same order, except that the group A8 = ''A''3(2) and ''A''2(4) both have order 20160, and that the group ''Bn''(''q'' ...
