5 pages. The revised version of the paper gives a sharper version of the counterexample, in the sense that it is generated by a set of cardinality 2^{\aleph_0} rather than 2^{\aleph_1}. This allows for a less set-theoretically technical argument, although the proof of primality is slightly trickier
