  title =         "Independent Axiomatization and Its Relation to the 
                   Hypersimple Set",
  volume =        "14"}

which contains a surprising characterization re independent recursive
axiomatizations.  I posted this before, but didn't see it appear.  If you've
already seen my posting on this, sorry about the repetition.
