No, as RAS has just been discussing with me, you can easily spawn off two
extents of Singles from a touch of Stedman Triples:

Six one is:

 1234567
 2135476
 2314567
 3215476
 3124567
 1325476

and six two is:

 1324567
 3125476
 3214567
 2315476
 2134567
 1235476

Put these together *at the level of individual changes* and you get the two
extents of singles:

 1234567
 2134567
 2314567
 3214567
 3124567
 1324567

and

 1235476
 2135476
 2315476
 3215476
 3125476
 1325476

Do you see the problem now?

Yes, this is perfectly reasonable. But the point is, the Doubles changes
would have to be treated as Max/Cinques rows, and proved against the rest of
the peal as such. If you don't do this, the peal is false.

Have a sit down and think about it Matthew...
