We can deduce from AC the assertion that every vector space has a basis 
and that the bases all have the same size.  One of my students pointed
out to me that Wikipedia claims that this uniqueness of size of basis
(= dimension) is actually equivalent to the Prime ideal theorem.  Is the 
author of the wikipedia article on this list by any chance?  Failing that, 
can anyone supply a proof?  (I asked Andreas Blass but he was away from 
his papers)
