Query: Flavour symmetry as a Spontaneously Broken Discrete Permutation Symmetry
  Embedded in Colour   A new mechanism for breaking an internal symmetry spontaneously is discussed,
which is intermediate between the Nambu-Goldstone and Wigner modes of symmetry
breaking. Here the quark-antiquark sea takes the role of the vacuum of the
Nambu-Goldstone case. Flavour symmetry becomes a discrete permutation symmetry
of the valence quarks with respect to the sea quarks, which can be
spontaneously broken without generation of massless Goldstone bosons.
