Hans, Thanks for that comment.  If we don't have an explicit construction
for any of the 8 "tours", how can we be sure that they don't get trapped
after a while?  (Compare the tours I talked about in the Numberphile video
on Youtube)

Thanks also for the MO link. I only read the start, so far, which seems
very sketchy and

Best regards
