In group theory, the symmetry group of a geometric object is the group of all transformations under which the object is invariant, endowed with the group operation of composition. It is very restrictive because it has implications for both the association between the variables and the margins of the table. Also, spectral plots of real signals are normally displayed only. It says that the spectrum of every real signal is hermitian. While i havent seen anyone explain why, theres a set of mathematics that goes about describing it called dynamic symmetry.
