	Group theory
		Möbius in 1827, although he was completely unaware of the group concept, began to classify geometries using the fact that a particular geometry studies properties invariant under a particular group.
		Hölder was to prove it in the context of abstract groups in 1889.
		At that time the only known groups were groups of permutations and even this was a radically new area, yet Cayley defines an abstract group and gives a table to display the group multiplication.

	Order (group theory) - Wikipedia, the free encyclopedia
		the order of a group is its cardinality, i.e.
		If G is a finite group of order n, and d is a divisor of n, then the number of elements in G of order d is a multiple of φ(d).
		Group homomorphisms tend to reduce the orders of elements: if f : G → H is a homomorphism, and a is an element of G of finite order, then ord(f(a)) divides ord(a).

	Order theory - Open Encyclopedia (Site not responding. Last check: 2007-11-06)
		Order theory is a branch of mathematics that studies various kinds of binary relations that capture the intuitive notion of a mathematical ordering.
		The first order that one typically meets in primary school mathematical education is the order ≤ of natural numbers.
		These are graphs where the vertices are the elements of the poset and the ordering relation is indicated by both the edges and the relative positioning of the vertices.

	20: Group Theory and Generalizations
		Group theory can be considered the study of symmetry: the collection of symmetries of some object preserving some of its structure forms a group; in some sense all groups arise this way.

	Order - Wikipedia, the free encyclopedia
		Order (from Latin ordo "row, rank, series, arrangement", Old French ordre from the Latin accusative, ordinem, attested in English from the 1220s).
		The word conveys a notion of "a system of parts subject to certain uniform, established ranks or proportions", an idea very central to scholastic thought, and it was used in a wide range of contexts, from architecture to angels.

		A group G is said to be a finite group if the set G has a finite number of elements.
		Let G be a group, and let H be a subset of G. Then H is called a subgroup of G if H is itself a group, under the operation induced by G. Proposition.
