Six couples to a set, alternating as heads, sides, heads, sides, heads and sides. Dancers form sets in an actual hexagon formation and all set-ups to a Triangle Square start with heads or sides leading to the right to form three lines (each of which is one side of the triangle). Bend the line will give the set a Y-shape. There are no numbered couples. As in the case of Hexagon Squares, a Grand Right and Left takes seven hands to partner.
