	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.
		Groups acting on topological spaces are the basis of equivariant topology and homotopy theory in Algebraic Topology.
		Nielsen's theorem: subgroups of free groups are free.

		Combinatorially, we view this class of symmetric tensegrities as having one vertex for each element of the underlying group G and 3 combinatorially distinct basic edges (or edge pairs, really) coming out of the basepoint vertex.
		The catalogue is organized by the type of abstract group of symmetries of the underlying tensegrity.
		But one must realize that for each of these groups, there is more than one representation of that group as a group of symmetries of a Euclidean space.

		The most important knowledge for a permutation group is a base and a strong generating set with respect to that base.
		One of the things that are very easy for symmetric groups is the computation of centralizers of elements.
		This is very easy, because two elements are conjugated in a symmetric group when they have the same cycle structure.

	Symmetry Group (Site not responding. Last check: 2007-11-06)
		Thus when we are considering the symmetry group of such a figure we may suppose G to be generated by rotations and, perhaps, reflexions.
		It is easy to see why the symmetry groups are the same; for the centers of the faces of a cube are the vertices of a regular octahedron, and the centers of the faces of a regular octahedron are the vertices of a cube.
		It is a matter of great interest and relevance here that the symmetries of the Diagonal Cube and the special braided octahedron of Figure 7 and Figure 16, respectively (of [Rec]) each permute the four braided strips from which the models are made.

	NONCOMMUTATIVE CHARACTER THEORY OF THE SYMMETRIC GROUP
		A new approach to the character theory of the symmetric group has been developed during the past fifteen years which is in many ways more efficient, more transparent, and more elementary.
		In this approach, to each permutation is assigned a class function of the corresponding symmetric group.
		The three detailed appendices on group characters, the Solomon descent algebra and the Robinson—Schensted correspondence makes the material self-contained and suitable for undergraduate level.

		Their study may touch a number of areas: Markov chains, random walks, statistics, asymptotics and algorithmic group theory.
		In particular, we outline the complex Schreier-Sims algorithm and its importance in solving polynomially many problems in permutation groups.
		A well-known theorem shows that, probabilistically, the symmetric group can be very easily generated using two random permutations.
