Goodness, what a lot of discussion.

Stuartn, if it helps, simes's original suggestion was utterly and completely correct, as was his transcription of the solution log from the Sadman programme. Any confusion would seem to be arising from somewhere else.

My disjoint subsets are now well informed. Thanks. - perhaps it may be better to describe multiples as either hidden, naked or 'partial' - rather than 'disjoint subsets' - which they may well be - but it's hardly a helpful description and just enhances the public perception that solving the hard ones is some sort of 'black art'. Which it isn't - not if people have made the logic clear and unambiguous in their explanations.

Rant over. Gin needed.
