Web2. The Mathematics & Physics of Permutation Symmetry. 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).
