There is just one way to go from XXXXOOOO to XOXOXOXO in five moves if *three* adjacent coins are moved at each turn. How?

(In reply to Question and Guess (spoilers) by nikki)

It took me a while, but I totally see your point, Nikki. And I vote for your first view. It explicitly says that only three adjacent coins can be moved at once, and the "squeeze" view point has lots of coins moving.

So ... if there is a blank space between coins, are they still adjacent?

And note: Nothing says move means translate; can we rotate three? I bet that is not intended ;-)
