> This dance is highly symmetrical and presents rotating double triangles in such a context where the second half of the
> figure is identical to the first half, only being rotated 90° anticlockwise so that the double triangles position is up and
> down the set (as is found in crown triangles). No dancers require a change of direction so the dance flows from one
> figure into the next and into the final circle round and back, making this an ideal dance for the end of the evening.

> turns which, in this variant, retain their original nature of being a three-quarter turn to the right for each
