Quark Summary                   (compiled from a number of different sources)
In addition to the three confirmed Omega particles, each of which comprises two or three strange quarks, theory predicts a large number of other types of omega baryon that have not been observed yet, as indicated by "unknown" in the right hand table.  Omega baryons are always combinations of strange, charm and bottom quarks.
