Permutation symmetry is a discrete symmetry supported by the permu-tation group Perm(X) of bijective maps (the permutation operators, Pˆ) of a set X onto itself.1 When X is of finite dimension Perm(X) is known as the symmetric group S n (where the nrefers to the dimension of the group).

WebJan 7, 2003 · Permutation symmetry is such a discrete symmetry arising as the mathematical basis underlying the statistical behaviour of ensembles of certain types of … WebIn the LWC basis, we have permutation symmetry S n 1 × S n 2 giving to two classes of operators, those that leave the two H 2 molecules together that is bi-cyclic operators like (12)(34), and those that move the individual H 2 molecules that is, monocyclic operators like (12) which is the same as transposition in group theory. morrow motors inc

http://www.pas.rochester.edu/assets/pdf/undergraduate/representations_of_the_rotation_groups_so-n.pdf The symmetric group on a set of size n is the Galois group of the general polynomial of degree n and plays an important role in Galois theory. In invariant theory, the symmetric group acts on the variables of a multi-variate function, and the functions left invariant are the so-called symmetric functions. In the representation theory of Lie groups, the representation theory of the symmetric group plays a fundamental role through the ideas of Schur functors. In mathematics, a permutation of a set is, loosely speaking, an arrangement of its members into a sequence or linear order, 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.
