text: This symmetry, “discovered” by W. Heisenberg in 1926 in relation to the indistinguishability of the “identical” electrons of an atomic system, is the discrete symmetry (i.e. based upon groups with a discrete set of elements) at the core of the so-called quantum statistics (the Bose-Einstein and Fermi-Dirac statistics), governing the statistical behaviour of ensembles of certain types of indistinguishable quantum particles (e.g. bosons and fermions).
