Degeneracies in Supersymmetric Gluodynamics and its Orientifold   Daughters at large N
  I use the Nicolai map and ensuing (super)locality of appropriate correlation functions to prove the existence of an infinite number of degeneracies in the mass spectra and decay coupling constants in supersymmetric gluodynamics and its daughter orientifold theory at large N.
