True - but a maximum of 10 that can be included in an extent.

Yes; only one though I think - the xxxx12/345612. All variants of the 
123/345 wrap are still in theory possible.

This must be a good time to bring out Rapid Wrap from hibernation...

Rapid Wrap Major
36.18.56.38-3458-34-56-78 = 23456781

 From memory there were 9 or 10 wraps of rounds in the plain course.

Also there were:

Rapid Rap Minor
-3-34.6.34-5 = 612345

Rabid Wrap Maximus
2.38.9.0-1-3.4.50.29.3456-7890-E = 67890ET12345
