Deviser's Note: 1c can choose handing freely ; the timing is fluid, the barring only an approximation
note: the set keeps a longwise shape
note: 3c does not move on bars 1-8.
5c (dancing couple) stands facing 1c in centre of square set, numbered clw as usual.
after 5 times through, 5c finish in the middle, all other C have moved one place clw
Repeat with a new top couple
